Hello,
I just registered to these forums but already visited this place for a while. I have a question that fits this particular subforum (I hope). It is related to another hobby of mine, which is knife collecting/making. Let me give you first some background info on the subject, in order to better explain the question.
A knife blade is usually made of steel, and brought to it's particular shape either by "stock removal" (grinder, mill, files ...) or forging. The knifemakers that forge to shape are saying this method has several advantages, like bringing the raw steel to a more homogenous state, "packing" the crystals closer and getting a crystalin structure that shows smaller "grain".
My question is: by taking a big bar of steel (like roller bearing steel 52100 or spring steel 5160) that has a diameter of let's say 20cm, getting it hot enough and forging it down to a blade size (using power hammers, repeated heat cycles), what changes in the steel structure might one expect? In particular, is there ANY change in density possible?
Thank you in advance for any clue or answer.
