Activation energy for serrated flow in type 316L(N) austenitic stainless steel

Tensile tests were performed at a wide range of strain rates (3.16×10−5−3.16×10−3 s−1) and temperatures (300–1123 K) to examine serrated flow behaviour, an important manifestation of dynamic strain ageing (DSA), in type 316L(N) austenitic stainless steel. The steel exhibited distinct low and high temperature serrated flow regimes separated by a retardation bay. Based on the activation energy value of 115 kJ mol−1, diffusion of interstitial...
