Abstract
Tensile tests of SUS3O4 austenitic stainless steels were done. We investigated strain rate dependency of fracture elongation, slope of strain hardening rate and environment temperature and characterized defonnation behavior of transfonnation induced plasticity. At low strain rate, a step-like change of fracture elongation was found on the SUS304 specimen at room temperature, 5×10^<-4>s^<-1>. Then correlation has been found between fracture elongation and slope of strain hardening rate.
