Hydrogen embrittlement can occur in steels with metastable phases, due to activation of the hydrogen-enhanced decohesion mechanism upon transformation. Meanwhile, recent investigations suggest that alloys undergoing ε-martensite transformation may exhibit resistance hydrogen embrittlement. To better understand effects these alloys, we investigate hydrogen-induced microstructural transformations...

The aim of this work is to derive the behavior for an austenitic single crystal from which the overall behavior of polynystalline TRIP steels can be deduced using classical scale transition method. The micromechanical modeling is based on the kinematics, kinetics and continuum-thennodynamics of the martensitic transformation. Plastic strains of product and parent phases as we11 as the volume fr...
