Is there any difference between work hardening and strain hardening?

In strain hardening hypothesis, the size of the yield locus is assumed to beindependent of the third invariant.In work hardening hypothesis, the size of the yield locus is assumed to depend on the total plastic work done (per unit volume) to achieve the present state of plastic deformation since last annealinfor isotropic hardening Both are same.


Is the steel strain hardening exponent temperature dependent?

yes, with increased temp, the s.h.e decreaseshiAccording to your answer . I must say that as I know , when we anneald metals ( e.g. Iron ) the S.H.E increased while you can decreas it by cold-work .


What is case hardening?

Case hardening or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material's surface, forming a thin layer of a harder alloy.

In metallurgy what is hot shortness in steel?

The term is used for character of steel, which become brittle at hot working temperature ie above 0.6 Tm (recrystallization temperature, where strain hardening is removed ) hot short hinders in hot working operation, often caused by the presence of sulphur in metal.
