Numerical investigation of the effect ofrate-sensitivity, non-octahedral slip and grain shape on texture evolution during hot rolling of aluminum alloys

Based on texture simulations with a viscoplastic self-consistent polycrystalalgorithm, this contribution presents a comprehensiveinvestigation of the effectof the rate-sensitivity exponent, the relative strength of non-octahedral slipmodes as well as the grain shape on texture evolution. The simulations arevalidated with texture measurements ofsamples from the industrial hot rollingprocess at different rolling reductions.Simulated textures at different hot rollingtemperatures are compared with experimental findings from the literature. Thepresent investigation indicates, that texture simulations must include three non-octahedral slip systems, use temperature dependent rate-sensitivity exponentsand account for the evolution of grain shape
