DYNAMIC STRAIN AGING BEHAVIOR OF K40S ALLOY X.F.Sun1,F.M.Yang1,Z.Q.Hu1,H.R.Guan1 (1.Institute of Metal Research, The Chinese Academy of Sciences, Shenyang 110016, China) Abstract:The dynamic strain aging behavior during tensile tests of K40S alloy has been investigated in the temperature range of 25-1100℃ with the strain rate range from 10-4to 10-3 s-1. The results show that four different......
