Deformation History Dependence of Flow Stress for a High Nitrogen Bearing Austenitic Stainless Steel

摘要

Flow curves of a stable austenitic stainless steel, SUS310S, a low temperatures have successfully been described by using Kocks-Mecking model, where the evolution of dislocation structure hardly depends on straining history. Alloying of nitrogen to such a steel causes straining history dependence of flow stress, but quantitative discussion has not been reported yet.
