As a person from Damascus, hats off for getting the date of Timur Leng's sacking of the city right. He beheaded so many people he practically depopulated the city, then he built massive towers with the severed heads, at the site of one of these towers there is a neighbourhood, outside the historic door of Tomas, still called Borj al rous which literally translate to the tower of heads.

Wootz is true Damascus. The pattern wielded garbage being sold and up-priced by blade smiths does not have the same structure and is in fact inferior steel compared to the nano structures found in true Wootz Damascus steel. The only other steel manufacture I can think of that would even come close would be Damasteel, but that is using modern powder metallurgy steels made in a pattern wielded form.

True. But unless you know how to smelt it it's more or less out of reach to the average smith. Now, nobody can say that a traditional katana is garbage, but it's not "pattern" welded per se, just forge-welded and folded.

pattern welded steel is the sparking wine of damascus.

Wait, how did the carbon nano tubes get in there? That’s the most interesting part here. Also, what forging process lead to the high carbon wires?

@ghoulishgoober3122

Жыл бұрын

It's probably just, the way wootz steel works, when it's heated up it "crumples" and forms those wires at some point, or that's what happens after it gets hit with a hammer. This could also be from the acid treatment or whatever they do with Damascus.

The mechanism of formation of the carbon nanotubes and the cementite nanowires is still not fully recognized. There are a couple of theories being floated at the moment, but no one actually knows. I will refer you to the research papers for those. I can tell you that the nanowires align down the length of the blade during forging. The cementite wires are broken into smaller pieces during the forging process at high temp and orient lengthwise down the blade as the steel is drawn out from the ingot into the blade.

The short answer is the Vanadium content of the ore from two particular mines in India and Syria, along with just the right processes in making the crucible steel with the right amounts of carbon, and then working the steel at the right ranges that incidentally caused the carbon nanotubes to form nucleation sites around the edges of the lattice when the steel was quenched.

@@TheKnifeLifeChannel Correct me if I'm wrong, but that was the best concise answer I couls conceive, based on what I learned from Al Pendray's work... but there may be newer discoveries that you've learned in the couple of years since I stopped smelting. The raw materials costs got too high for me once the pandemic killed the supply chain, lol. Great video, sir.

My question is which version is better? And what in modern metallurgy has surpassed it, if anything? And if not, why is it not very common today (at least so far as I understand)?

@TheKnifeLifeChannel

In general pattern welded steel tends to be stiffer, and wootz tends to be tougher. Unfortunately I don't have a wootz blade to play with myself and I don't have exact numbers to give you in terms of its mechanical properties. There was a dedicated effort led by Pendray and Verhoven to figure out how to make wootz in mass. There is a lot of potential for it in things such as leaf springs if you could mass produce it. As of yet it can be made in a low tech dirt floor foundry and smithy in small batches, but there hasn't been any success in industrial scaling up to the best of my knowledge. In comparison to modern steels, the problems pattern welded steel worked around have been largely dealt with via improved heat treating and superior "space age" steels. Wootz is likely still more relevant, but would be hard pressed to compete.

Tamahagane, which is bloomery steel. It is actually some of the worst steel that you can produce by today's standards, but is traditional in making katana. Most of the steel is used in making other tools and only select pieces are used in making the katana.

The Japanese harvested steel from the soil, surface mining, and meteorites. All were shit. From the soil and mining they got what we'd call pig iron, and meteorite metal is HEAVILY contaminated with nickels, silvers, and golds you can't just cut away from the iron and other desirable metals.

Mainly because people need something to argue over for their own entertainment. Another interesting piece of information is that pattern welded steel tends to be stiffer, whereas wootz is liable to be springier. As you know, each have their own place.

I love the fanatical pro-wootz comments ranting and raving that pattern welded steel is shit and not real Damascus because Wootz is better. Its like they ignored the premise of the video and think the premise is about establishing which steel is best and then slapping the Damascus name on that one. Why are they such staunch Wootzers anyway? Are they Indian? I'm intrigued.

Wootz does actually display a pattern after acid etching similar pattern welded steel. It isn't as dramatic of an effect, but it is there. That pattern is a source of some of its nicknames such as "watered" steel.
