Role of Deformation-Induced Martensite in TRIP Effect of Metastable Austenitic Steels

Role of deformation-induced martensite in the transformation-induced plasticity (TRIP) metastable austenitic steels was studied by examining effects temperature on tensile properties Fe–18%Cr–6%Ni–0.2%N–0.1%C (6Ni–0.2N–0.1C) steel. The obtained tests at various temperatures between 123 and 373 K were compared with those SUS304 0.2% proof stress, strength, uniform elongation 6Ni–0.2N–0.1C steel larger than all studied, mechanical stability austenite for higher that Neutron diffraction experiments room showed improvements associated work hardening strength martensite. increase N C additions leads to better due TRIP effect, despite smaller amounts martensitic transformation.
