| Abstract Scope |
Despite decades of study the mechanisms behind the development of cube recrystallization textures in fcc metals are still debated. In this work, we used dislocation-based crystal plasticity study the lattice rotation of non-cube orientations under plane strain compression to revisit classic recrystallization studies from Driver, Doherty, Samajdar, and Juul-Jensen. We find that as single crystal non-cube orientations do not rotate towards cube under ideal plane strain compression. In contrast, the same non-cube orientation develops cube-oriented fragments in polycrystals. Analysis of micro-mechanical fields reveal that the local deviation of the RD-ND shear component leads to a remarkable change in the slip system activity which promotes cube development. For the general case of a polycrystalline microstructure, deviation of the RD-ND shear component shows the highest correlation with the development of the cube orientation in the non-cube grains. |
