摘要
•Strain rate and temperature sensitive strain-induced austenite to martensite transformation laws are developed.•The laws are incorporated into an elasto-plastic self-consistent crystal plasticity-based finite element model.•The model is used to simulate deformation of wrought and additively manufactured 304 L steels during tension, compression, torsion, and impact.•Geometrical features, strength, and microstructures in terms of spatial fields of phase fraction and texture evolution are predicted.•Strain path, strain-rate, temperature, triaxiality, and initial microstructure and texture sensitivity of martensitic transformation is interpreted.
