>> No.42194621

I can't speak to any special properties, given that I've never worked with magic blades, but the liquid you use for a quench absolutely affects the end product. Different liquids have different thermal properties, changing how the steel cools. Fresh water makes for an inconsistent quench, since bubble formation as the water heats up interferes with heat transfer, leading to soft spots. Salt water doesn't have this problem, but you have to be careful about metal corrosion. Oil cools the steel slowly, making for a softer but less brittle blade. Glycol polymers can get really fine control over the tempering by adjusting the solution, but require constant attention. I know some cutlers have tried tempering with things like wine or lamb's blood or whatever, but I've never worked with those.

>> No.42194625 [DELETED] 

The different liquids harden the steel at different rates. Oil will harden the steel slower than water, and clay is slower still. Brine and water are the fastest.
The liquid you use to quench it depends on what kind of steel your using, and what you want it to do.

>Would the type liquid the blade is quenched in affect the end product?


Quenchants have various speeds - amounts of thermal reduction per second. they're not always obvious.

liquid nitrogen, for instance, is quite capable of freezing something far, far below the freezing point of water - but its actually really shit for quenching, as it boils, forming a jacket of gas around the metal - so it cools the metal very slowly.

Water cools rapidly, salt-water (brine) cools a little slower. Oil cools slower still.

Technically, molten, liquid lead can be used for a quench, though I've never seen it done. Apparently it was used by Wilkinson in the 19th C.

a lot of the mythology of swordmaking revolves around the heat-treat and quench. One manuscript on the subject calls for the urine of a red-headed virgin boy. Another calls for the urine of a goat that's caged and fed fennel for 7 days before its piss is collected.

Historically, whale oil was used.

Metallurgically, a faster quench is more likely to create a hard steel, but it risks it breaking the blade - thermal shock can cause cracks to propagate through the metal.

>I know some use oil, though not why.
Oils allows for a faster cooling rates of the metal since oils can reach higher temperatures before boiling. Brine solutions are also sometimes used for similar reasons. The rate at which the metal is cooled partly determines the microstructure of the metal. Rapid cooling is needed for the austinite to martensite transformation to occur. See pic for the time-temperature transformation plot of 1080 steel.

An a side note, EXTREMELY fast cooling of some metals allow for amorphous phases which have some enhanced properties such as higher hardness and elasticity than typically possible with metals. The downsides include low temperature stability, lower toughness (the energy required to fracture), and the parts typically having to be of certain shapes to allow of the rapid cooling rates. For example the first amorphous metals were formed by pouring the metal onto spinning metal cooling drums to form ribbons of the amorphous metal.

>> No.42194795

the quenching liquid just determines the speed at which the blade cools, while it is true that quenching in oil will add some carbon to the blade, the most this could penetrate is about 1mm, and it's not a sufficient amount of carbon to really effect hardness. 95% of the work done to make a blade is done well before you quench.

I would assume it allows for a fast quench but limits the minimum temperature of the quench to the temperature of the molten lead it kept at which can be anywhere from 327C to 1749C.

>> No.42195043

Different anon here, expanding upon this;

Which liquid is most suitable for quenching depends on the type of steel.

Steel gains higher strenght from higher concentrations of carbon and other such impurities in the metal lattice. These foreign elements interfere with the way the metal atoms can slide around the lattice, thereby making it stronger and harder. Carbon is the most common of such introduced impurities.

In short, low-carbon steels can be quenched in water, medium carbon steels in various oils and some of the highest carbon steels can even be quenched by blowing cool air over it, if the part isn't too thick.

Generally, parts that need to be hardened are medium carbon steels, so oil is most commonly used. Some precision tools can be made of very hard high carbon steel to prevent both wear and simple elasticity from influencing measurements and processes. These tools are to be treated with care because the harder a steel is, the more fragile to shock it becomes (you can break some steel parts and tools of this sort simply by dropping them).

>clay is simply an insulation layer, so that the covered area is cooled slower. the same thing can be done in a few ways.

The clay works in two ways.

The rough surface of it increase heat transfer to the water, IIRC by helping keep the steam bubbles (which insulate) small and quick to bugger off.

The body of the clay on the other hand insulates.

So a thin clay layer increases the effect of the quench, while a thick one insulates to keep things unhardened. With traditional Japanese sword making the edge gets a very thin coat, and the body a thick one.

>For example the first amorphous metals were formed by pouring the metal onto spinning metal cooling drums to form ribbons of the amorphous metal.
I did that once. It eventually turned out that the magnetic properties of amorphous metals can make those shoplifting alarms go off.

As for cooling rate, in addition to the transformation to martensite in general a rapid cooling will tend to produce a finer grain structure, which is almost always a very good thing. The downside is that the quicker the quench the greater the risk of thermal stress ripping the blade to pieces.

Molten lead is far too hot to turn "basic" steels to martensite, ie normal hardening, but going by the TTT diagram in >>42194759 it would allow you to make a bainitic steel. 19th century sounds a bit early though. Maybe it was just for tempering or normalisation and someone got it mixed up with the quench.

Using iron, carbon and steel as the example, if we start adding an alloying element to a metal it, at least generally, makes it harder. If the added atoms are in a solid solution then we call it solution hardening. if the added stuff forms small particles within the metal, either on their own or of a mix of the alloying element and the base metal, then, hm, I think precipitation hardening was the technical term, so we'll sue it for now. In either case, the individual atoms or the particles present obstacles as "dislocations" try to move around in the metal, and dislocation movement is a major mechanism when a metal deforms, so it gets harder.

As we add carbon to iron, only a very minor amount will dissolve in it, while the rest forms iron carbide particles. So precipitation hardening is dominant.

Now quench hardening of steel works in a slightly different way. Now the base iron has the atoms stacked in a certain way. The smaller carbon atoms that are dissolved into it slip into the empty spaces left over. Iron carbide also has the atoms stacked a certain way, this time with the carbon atoms given proper places too. What we do when we quench harden is that we force the steel into an entirely different stacking of the atoms, which ends up being a stretched-out form of the one pure iron has, with the carbon jammed in here and there. This new stacking variant is a lot stronger than what we had before. While adding 0.8% of carbon to iron can increase the hardness from 146 Brinell to 174, quench hardening of that steel can then push it past 700. While one could consider that hardness increase to be at least in part due to solution hardening since all the carbon is now dissolved, the stretched out BCC stacking style certainly carries part of the blame as well here, and the role of the carbon is in many ways enabling that stacking much mroe than it is there to provide solution&precipitation hardening.

Really, only in the temper. Water works really well, but cools the metal just a bit more rapidly than is ideal. Oil is marginally better, and is theatric. Which was important to some smiths, before they were more common than one per five or ten towns. They turned rocks into swords and tools, shit was magical. They'll put your ancestor's bones into the crucible, so the great warrior spirit of your grandfather can aid you in battle. Then bind it to you alone by mixing your blood into the oils used to quench the blade and holy shit your new sword is on fire how cool is that?

My guess is that the mercury in contact with the sword would quickly boil way, and the boiling point of mercury is the temperature that the steel would be quenched to. This being 357°C, most steels won't turn martensitic.

If you're really lucky, and have a lot of mercury, then the mercury would be able to conduct away the heat quick enough that it won't boil, and the temperature the steel is quenched to end sup being a bit above room temp. This could allow for some very hard steel, but would also be an extremely harsh quench if it happened, and thus very likely to destroy the object.

Unless the ice chunk has a perfectly blade-shaped slot in it then you're not going to manage much contact between blade and coolant. What little do touch might get a kinda severe quench (but if it's too little heat heat in the blade around might stop even that) while the rest just air-cools.

Now if you do have a suitable slot the blade will probably quickly melt away the ice in contact, and then boil off the water. That leaves our blade out of contact with the ice, dropping the cooling rate to "not enough". One great advantage of liquid water here is that it automatically replaces the water that boils off, ice can't do that.

Now if we somehow managed to keep pressing the blade into the ice to supply it with fresh coolant, or maybe if we just managed to supercool liquid water and quench in that, then the result will be an extremely harsh quench, likely to shatter most steel grades. With very specific shapes to quench, extremely good quality, and so on you might manage to make a very hard steel (with just decent percentage shattering), but tempering that down to being less brittle than window glass will remove most of that.

Bodily fluids are approximately salt water. But compared to quenching in a tub of that the bodily tissues prevent the free flow of liquid and steam, so the cooling rate would quickly drop as the locally available liquid boils off, leaving you with at best a blade which only has the outermost skin quenched.

As cold as it is, it might not be a very effective cooling media.

Water has a relatively high heat capacity, so it takes a lot of energy to heat it from room temperature to boiling. And it has a very high heat of vaporisation, ie it take s a huge amount of energy to go from 100 degrees hot liquid to 100 degrees hot steam. This allows water to very quickly remove a lot of heat from something.

Nitrogen on the other hand doesn't consume nearly as much energy as it boils, and the nitrogen gas that's produced isn't going to absorb significant amounts of energy.

So the cooling in nitrogen might be to slow for anything of note to happen, even though it'll eventually get the steel extremely cold.

I did this with my 5e campaign. If you wanted to make a magic elemental weapon you had to 'quench' it in a place of significance to the element. You wanted a Flamue Tongue, go quench it in a pool of lava at the heart of a volcano. You want an Ice Brand, go quench it in a glacier from before recorded time. It was either that or capturing an elemental of the right type and negotiating an agreement for it to lend you its power.

That and including the risk of the blade literally exploding in the prosess due to the tension when the inner layer of metal cant keep up with the outer hardening. Seen it happen once. Dangerous shit.

Anyway. Generally speaking the process of hardening depends lot from the quality of the steel, thickness and the overall quality of the smithing (number of times reheated mostly). Preheated oil is the most commonly used by professionals, but some tend to do their own mixes of liquid (i have heard of some using ingredients such as: Honey, coffee, tea, urine, feces, cooking oil, egg white, river water, alcohol and numerous of other things) Some of such recipes can be generations old and still be used even if they dont have proper evidence in their claimed superiority. It is rather interesting really but as said somewhere i read once: effects of suggestion can alter the way the tool is used and that way make it better than others equally well made items.

The function of the quench during swordsmithing is to convert austenite to martinsite. Just making the steel hot then cold isn't the only part that is important. The starting temperature is important since the steel needs to be austenite, the rate of cooling is important since the austenite to martinsite transition has to be diffusionless, and the ending temperature is important since the steel needs to be too cold for any diffusion to occur following the quench to maintain the martinsite microstructure.

So, in theory, only liquids that can cool a sword to below about 400C can be used. Anything hotter than about 400C will cause diffusion in the steel forming pearlite which is much softer than martinsite.

I'm sure that there are more efficient chemical ways to do this, but if you're doing it on the cheap your best bet is to use certain types of bacteria. "Bog iron" is a type of low-quality iron ore found in swamps as a byproduct of bacteria that metabolize iron compounds. It's not too high quality, but it has the advantage of being easily extracted. Anyway, you're going to want to let the blood decompose to free up the iron in it, then once you've done that introduce ferrophilic bacteria into the culture. It will be a slow process, but it will work. As a plus side, the residual silicates will make the blood sword resistant to rusting.

Presumably, it would require a lot of energy. And a lot of people.

An average, well fed male contains approximately 4 grams of iron. Total. Thus, assuming you could extract every single molecule of that and collect it, you'd need about 500 people to produce 2 kg iron, which is on the very low end of what you need for a sword.

Next, consider the iron bound in molecules. In a heme b group, the single iron is bound between four nitrogen atoms. Both iron and nitrogen is known to produce strong bonds, so it's not completely out of the picture that breaking these bonds would require quite a bit of energy. Mind you, I don't know how much of this particular molecule there is in blood, nor anything else for that matter, it was just an example I found.

not in the grand scheme of things... It sounds like whether or not you use water or oil may impart some small change to it's properties but not likely enough to affect its stats in most gaming systems.

I think you would get far more interesting properties by changing the material used than how it's cooled afterwards.

dunno where you got 50mg to a ml from but the normal estimate is 250mg to a pint (way way less). plus the blood doner people say that you should wait 16 weeks between pint donations, and given that the bit with the iron is the bit that takes the longest to replenish and given that anyone trying this would be keeping up the transfers for a long long time you probably wouldn't wanna undercut the safety guidelines by more then a week at most. in 2 years you would have more like 1.7g of iron not 1.5 kg.
However... as>>42197366 says you probably loose about half of the iron you can collect from blood in the forging process. and given the tiny amounts of metal you'd be working with in extraction loosing about a fifth of whats actually in the blood to one thing or another before forging doesn't seem unreasonable. If an immortal were to start collecting there blood at this rate at the very dawn of the iron age (call it 1200BC) they would have enough iron to forge a 1.1kg sword right about now.

A few thousand.
pointed out you need around 8,000 pints of blood before accounting for loss from forging, if you could extract all your blood without dying from exsanguination, you could get it down to 800, but most people die upon losing about half, and lets say you lose about half from wastage (from both forging and extraction you will lose quite a bit), it would therefore take about 3200 to make your sword.

I just wish to point something out. Using human blood to reduce to iron, and then smelt to steel, to forge a blade, using your numbers of 8000 pints of blood, is equal to approximately 4 TONS (short tons, 3.62874 metric tons) of blood. Just blood, not including containers of any kind.
Gathering that much in one place would be problematic enough, but this is literally 4+ PALLETS of liquid human essence(plus containers) and that shit is going to be a bitch to reduce and smelt.
I'm betting that the reduction process will garner a loss rate of AT LEAST 50% using non-magical, non-modern methods (and then probably electroplating or otherwise bonding the iron in a solution, for best results). Then you have really shitty iron to try smelt in to some not shitty steel. 15%+ loss just from the shit iron to steel (again, unless using a magical or modern process). Then you have all the little things during the actual forging and polishing and sharpening. You'll be lucky to get 50% blood to blade. It's always safer to have extra than not enough, might want to get a few more pallets of liquid people brought in.

weapons and armor made from this dull grey metal are treated as master-crafted and weigh 1/2 their weight, also any spell targeting an item made of aluminum or a person wearing aluminum armor automatically fails.

Shinier than polished mithril, and as expensive as platinum, Items made of Iridium always count as master-crafted and are impervious to all forms of corrosion, even by magic.

this black-colored metal has nearly the same profile as adamantium, which doesn't exist in the setting.

an odd brownish-colored metal weapons made from Uranium are heavier but if an opponent is struck by the weapon become poisoned, if the weapon is not carried in a lead sheath, then the wielder will also be poisoned after 24 hours.

weapons made from this unusual metal gain the fragile quality, but in the light of a full moon are treated as master-crafted

that's what I got so far, thoughts?

Not sure what the point of the aluminum magic immunity is.

>> No.42208416

Technically partially correct, but regardless of how sharp it is, its construction does lead to a single glaring flaw:

It requires technique to use. You have to draw it, fluidly, along the cut, or the impact will wreak havoc on it.

If you wield it like your standard European sharpened steel stick one of two things will happen. It will either fold forward unnaturally, or the layers of metal inside it will separate from the impact and it will break.

Because of how it's folded to remove impurities in the metal, it likely can't be reforged, because it will need to be folded again, and doing that too many times will wear down its durability and make it brittle, because of just how much it's being worked every time it is worked.

>Not sure what the point of the aluminum magic immunity is.
screw-ball logic, In every movie depiction of War of the Worlds, the Tripods are depicted as having force-fields protecting them, in the original book they didn't have force-fields of any sort, but from one excerpt it implies that the Tripods are made of Aluminum. So I went halfway and decided that Aluminum has some weird property that makes it behave like its encased in a permanent anti-magic field. Obviously it's screw-ball logic, but then magic is generally based on screw-ball logic anyway so I figured it'd fit right in.

I was actually wondering about metallurgy earlier this morning, particularly cobalt. I realize Iron and Steel are used for a reason and the reason is they hold edge, bend but don't break, and so on, but how would a situation dictate the use of other materials? If not entirely made of this other material, then perhaps alloyed with it. For example, Cobalt is very water and heat resistant, so I was thinking it would be used on the seas, in swamps, or something.

I have actually tried this, on a very low scale. I heated a basic mild steel rod to the point it was yellow, just before turning white and then becoming liquid.

I placed the rod upon a small block of ice, about 5" cubed. The sound was a hiss like when you stir water in a pan and the hot metal touches cooler water. There was no explosion, but from rapid expansion the ice did crack down the centre.

The metal rod became very hard, to the point that a simple bend test shattered the piece with about 150lbs of pressure.

I've heard Peanut Oil makes a decent quenchent for blades. True?

>> No.42210553

Quenching sets the grain structure of the iron crystals making the piece hard (good at holding an edge) but brittle. You can snap a piece of hardened steel over your knee like a branch. Then you temper it by heating it up to a relatively low temperature (400-450 degrees is a good knife temp) to trade some of that hardness for flexibility so your sword doesn't snap the first time it hits a shield. Different quenching agents cause the steel to cool at different speeds. Oil is preferred to water by a lot of modern smiths because it cools slower and leads to fewer stress fractures. Not all steels need to be oil quenched (or quenched at all, air "quench" steels exist).

In my opinion as an amateur blacksmith too much mysticism is put in the quench. It looks cool but there are better places to put in the magic. If I was making up a magic sword I would either have making the bloom (hunk of iron after processing ore) or the temper be the magic bit. Seriously cracking a Bloomery is amazing you shovel rocks in the top for 6 hours, then pull still glowing steel out of the thing.

You'll have to make a reason why everyone with enough money isn't wearing light aluminum armor. Magic Immunity is fucking powerful and every king, noble and priest would want it.
World wars would be fought over aluminum mines and sundering aluminum armor would be a capital crime. Aluminum would be considered, in setting, the best metal above even platinum, gold, adamantine and mithril.
Think about how it affects the setting before designing stuff, specially something like special materials.

>> No.42219197

>You'll have to make a reason why everyone with enough money isn't wearing light aluminum armor.
part of that is simply few know how to pull the metal from the clay. Just getting an aluminum bloom is an art requiring a powerful wizard apply constant lightning-based spells to a solution to draw it out, a technique that makes each ingot of aluminum more valuable than gold, and its an art that is all but lost. what few examples of aluminum armor and weapons that remains are relics from those days before the process was lost.

>> No.42219668

I don't think it would necessarily be that valuable. If it imparted immortality THEN it would be that sought after but people wouldn't go world war crazy for it. Plus it may make you immune to magic but it doesn't make you immune to having a boulder magically dropped on your head.
