Texture characteristics controlled by single slip plane slipping in the warm-rolled Fe-14Mn-5Si-9Cr-5Ni shape memory alloy

To clarify the texture evolution mechanism of Fe-Mn-Si-based shape memory alloys, the rolling texture of an Fe-14Mn-5Si-9Cr-5Ni shape memory alloy is investigated during rolling to a final reduction of 82% at 873 K. A new rolling texture caused by single slip plane slipping is observed from such alloy, which is different from the conventional copper-type and brass-type textures. By means of the {111} pole figure scattering analysis of the local deformation structure, we conclude that such single slip plane slipping results in the weakness of brass orientation in the a fiber and the great enhancement of β fiber connecting S′ {331}<213> and B′ orientations {110}<114>.
