Abstract

Evolutions of martensitic transformation and texture during cold rolling in novel bcc Fe-Mn-Al-Ni-Cr alloys were studied. X-ray diffraction (XRD) and electron backscattering diffraction (EBSD) analyses revealed that this alloy undergoes α → σ → γ′ martensitic transformation during deformation. At a 20% cold rolling strain, most of the a phase transformed into γ′, and the transformed γ′ phase had a Kurdjumov-Sachs (K-S) relationship with the parent α phase. Strong {hkl}<111> and weak {110}<001> transformation textures were formed after deformation. This texture evolution appeared to be related to the variant selection that occurred during the martensitic transformation.
