Features of Shear Banding in Grains with Orientation {111}<110> in the Fe - 3%Si Alloy

Abstract

EBSD method were used to study the texture of BCC crystals {111}<110> Fe-3%Si. It is shown that in the state after cold rolling shear bands with habit plane at a slope of ∼ 20 - 40 to the RD were formed as a result of 70% deformation. Theoretical analysis was performed and experimental data were analyzed which showed that the matrix reorientation into orientation {110}<001> occurs when grain stripping with orientation {111}<110>. Such effects are observed either due to rotation around the <100> axis or due to rotation around the <110> axis. By means of dislocation sliding, most of the SBs blocks are reoriented to orientations close to {111}<112>. © Published under licence by IOP Publishing Ltd.
