Abstract:

A model of the formation of shear bands upon cold deformation of \{111\}aOE (c) 112 > crystals of a commercial Fe-3\%Si alloy is proposed. The model suggests a two-stage mechanism for the formation of a shear band and its fine structure. At the first stage, there occurs an anomalous twinning in the \{114\}aOE (c) 221 > system; at the second stage, an almost complete secondary twinning of the band in two standard \{112\}aOE (c) 111 > systems occurs. As a result of these transformations, the shear band consists of regions with an almost cube-on-edge orientation \{11 11 1\}aOE (c) 1 1 22 > and an ``octahedral{''} \{111\}aOE (c) 112 > orientation, which is symmetrical with respect to the initial \{111\}aOE (c) 112 > orientation. A crystallographic mechanism responsible for an anomalous twinning in the \{114\}aOE (c) 221 > system by the slip of (8a/18)aOE (c) 221 > partial dislocations is proposed. It is supposed that the shear bands observed consist of groups of different numbers of shear microbands.
