Abstract

A modified Taylor model, hereafter referred to as the MTCS(Mechanical-Twinning-with-Coplanar-Slip)-model, is proposed in the present work to predict weak texture components in the shear bands of brass-type fcc metals with a twin–matrix lamellar (TML) structure. The MTCS-model considers two boundary conditions (i.e., twinning does not occur in previously twinned areas and coplanar slip occurs in the TML region) to simulate the rolling texture of Cu–30%Zn. In the first approximation, texture simulation using the MTCS-model revealed brass-type textures, including Y {1 1 1} < 1 1 2 > and Z {1 1 1} < 1 1 0 > components, which correspond to the observed experimental textures. Single orientations of C (1 1 2)[11 11 1] and S’ (1 2 3)[44 11 2] were applied to the MTCS-model to understand the evolution of Y and Z components. For the Y orientation, the C orientation rotates toward T (5 5 2)[1 1 5] by twinning after 30% reduction and then toward Y (1 1 1)[1 1 2] by coplanar slip after over 30% reduction. For the Z orientation, the S’ orientation rotates toward T’ (3 2 1)[2 1144] by twinning after 30% reduction and then toward Z (1 1 1)[1 0 11] by coplanar slip after over 30% reduction.
