Deformation induced martensitic transformation in a 201 modified austenitic stainless steel

The production of low nickel austenitic stainless steels has increased considerably mainly due to nickel price evolution in the last years. In the present work, the susceptibility to deformation induced martensitic transformation of a 201 modified stainless steel was evaluated. The results were compared to existing results of traditional AISI 304 steel. The variation of martensite volume fraction against true strain was modeled by a sigmoidal equation and the transformation rate was also determined.
