Notes:
The influence of crystallographic orientation stability on the inhomogeneous deformationon the meso-scale was numerically simulated with the crystal plasticity finite element. The initialmicrostructures were introduced into the finite element via intra-granular orientation gradient. Theresults demonstrated that the average orientation for both stable Goss and meta-stable cube orientedgrains changed very little in plane strain compression (PSC). And for stable Goss oriented grain, theorientation gradient increased slightly, but for meta-stable cube oriented grain, the orientationgradient increased dramatically. And in spite of the same Taylor factor for both oriented grains, thedissipated averaged energy for cube oriented grain was higher than for Goss oriented grains, and thedistribution width of dissipated work in cube oriented grain was also wider than that in Goss orientedgrain. Furthermore, there was also strong energy gradient in PSC of cube oriented grain. Both theorientation gradient and energy gradient favor the nucleation of cube grains during recrystallization
