FLOW STRESS OF UNSTABLE AUSTENITIC STAINLESS STEEL ACCOMPANIED BY DEFORMATION-INDUCED MARTENSITE.

Abstract

Flow stress ( sigma ) of unstable austenitic stainless steels was studied by comparing stable austenitic and martensitic stainless steels. The higher the strength and the larger the volume of alpha prime phase is, the higher non-uniformity of strain between gamma and gamma prime phase. The smaller the volume of gamma prime phase, the smaller the uniformity of strain between gamma and alpha prime .
