V. Subramanya Sarma,V. Subramanya Sarma,Jun Wang,Jun Wang,W. W. Jian,Alexander Kauffmann,Hans Conrad,J. Freudenberger,Yuntian Zhu +8 more
TL;DR: In this article, the effectiveness of the cryogenic rolling vis-a-vis room temperature (RT) rolling on strengthening is significantly affected by stacking fault energy (SFE) and there is an optimum SFE at which CT rolling is most effective.
