Abstract

The effects of nitrogen content on deformation-induced martensitic transformation (DIMT) in Fe–18Cr–10Mn–N alloys were investigated. During tensile deformation, the stress–strain response was changed at different transient strains (ε ≅ 0.19–0.22) depending on the nitrogen content. At the beginning of the deformation, a γ → ε martensitic transformation occurred, whereas the formation of α′-martensite was predominant after transient strain. Increasing the nitrogen content caused the transient strain for DIMT to shift to higher strain and, finally, DIMT did not occur when nitrogen content was above 0.5 wt.%.
