Peter has talked about hardening and tempering steel before, but this time he goes on a deep dive into the metallurgy as well as running a number of flex tests at different temper points.
pendray’s repeated thermal cycling is everything to the pattern of damascus. i am curious how the pattern is related to the different crystalline structures you describe, all those “ites.” i know you’re not making wootz necessarily, but i found it very interesting that the thermal cycles make him able to have pattern or not. he can even eliminate them and reintroduce them. thanks for the in depth read on the temperatures and behavior of the smallest structures. 👑 david i disagree. 500 degrees twice was harder and more brittle.
