Question about metalurgy

[Battleriflefan]

What would be the effect of Cyrogenically treating a forged blade, specifically, say a homemade sword blade. IIRC Kommander or someone was in the business, I can't remember exactly whom. If they answer, about how much would it cost?

How was the blade heat-treated after forging?
IME, cryo is the final "icing" of the hardening.

[HTRN]

I've heard that Cryo is supposed to improve edge retention. Downside is it also takes all the residual stress out of the blade, which can make it warp if it has a lot of it.

Depends on weight usually. You will get a couple more points of hardness as it will convert retained austinite to elemental martinsite while making it dimensionally more stable.

Further, your edge will last a whole heck of a lot longer. We have done some amazing tests. One day when I come up for air in the current cryo venture I will start another one dealing with edges. Right now springs and brakes have me all tied up.
