Evaluation of strain-induced martensite formation and mechanical properties in N-alloyed austenitic stainless steels by in situ tensile tests

In this study, the influence of various nitrogen contents (0.12–0.23 wt.%) on the mechanical properties, especially the strain-induced α'-martensite formation behavior, of the austenitic stainless steel X3CrMnNiMoN17-8-4 was investigated by temperature dependent in situ tensile tests. With the aid of in situ magnetic measurements during tensile test, the correlation between the strain-induced α'-martensite formation and the inflection points in...
