Evolution of Recrystallization Texture in AISI300 Series Austenitic Stainless Steels After Cold Rolling to Large Strain

Abstract

The present paper deals with the evolution of texture in austenitic stainless steels during annealing after 95% cold rolling. After 95% cold rolling, the texture is mainly of the brass type {110} <112> along with a scatter towards the S orientation {123} <634> and Goss orientation {011} <100>. Weak evidence of Cu component is observed at this high deformation level. During annealing, recovery is observed before any detectable recrystallization. After recrystallization, the overall texture intensity was weak; however, there are some discernible texture components. There was no existence of the brass component at this stage. Major components are centered on Goss orientation and Cu component {112} <111> as well as the BR component {236} <385>. Also, there are some few orientations which come up after recrystallization i.e. {142} <2 –1 1> and {012} <221>. With increase in annealing temperature the textural evolution shows emergence of weak texture with another new component i.e. {197} <211>. The evolution of texture was correlated with the deformation texture through twin chain reaction.
