Omega Transition Accompanied by Mechanical Induced Twinned Martensite in Medium Manganese Steels
The omega transition process was firstly analyzed combined with martensitic transformation in this investigation. In order to avoid the influence of auto-tempering on metastable omega phase, martensitic transformation process was inspired by deformation at room temperature. Omega phase was found only exist within twinned martensite with single variant, and the results indicate that omega phase formed by the lattice invariant twin shear during the dynamic transformation of twinned martensite. Besides, the nature poor ductility of twinned martensite was discussed.
