Abstract

Tensile tests, at temperatures ranging between 275 and 475 °C were performed in a superduplex stainless steel EN 1.4410. The dependence of yield stress and ultimate tensile strength on temperature indicates the existence of dynamic strain aging (DSA). In order to evaluate the influence of strain rate on this phenomenon, tests were conducted at two different strain rates, both at 325 °C, temperature at which DSA is maximum for this material. The results show that the flow stress has an inverse strain rate sensitivity which confirms the existence of DSA in the steel under study.
