When we do cardonitriding or casehardening operation for a plain carbon steel the case depth, hardness & microstructure are not alike why and what are the basicthing, which makes such a difference.

How does and why the recrystallization temperature of the metals affects on alloying?
Is there any way through hardening and anodizing some type of aluminum, it could be as hard as steel? I have hardened steel rollers that run up and down on a ramp along with spring pressure. Alternatively, if you are familiar with snowmobiles, the rollers run on the helix on the secondary clutch.
