Abstract

In stainless steels during the non-equilibrium transformation of austenite the deformed bcc α' martensite and hexagonal, non-magnetic ε martensite also can form. These transformations can be induced by cooling (under critical temperature) and/or mechanical deformation. The appearance of ε martensite has an effect on the deformation ability and other properties. The experimental results associate the ε martensite formation with the plastic deformation behaviour (TRIP effect), while the transformation of ε martensite into α' martensite is accompanied with hardening. The present phases hardly determine the cold rolling properties. During the deforming of α', ε, γ phases in stainless steels the texture also developes. The initial strong deforming γ texture changes with the appearance of α' martensite. We suppose that the transformation takes place at certain places in an anisotropic way due to the deforming texture. The texture of α' martensite develops by the initial anisotropy of parent phase and/or the phase deformation.
