The relative contributions of deformation modes to AZ31 rolling textures in different temperature regimes

Abstract

Key differences in the textures of cold-, warm-, and hot-rolled Mg alloy AZ31 sheets and plates are identified. It is shown that incorporation of compression twinning within Visco-Plastic Self-Consistent (VPSC) polycrystal plasticity simulations reproduces key features of the cold-rolling texture that have not previously been predicted. Discussion of recent observations of recrystallization and grain growth provide explanations for the hot-rolled texture. Finally, it is demonstrated that starting with the correct initial texture is essential to produce observed features in all the rolling textures, including warm-rolling.
