Softening Behavior

Due to the deformation mechanisms and the typical basal texture rolled magnesium sheets show a significant asymmetry of flow stress in tension and compression. In order to avoid this undesired behavior it is necessary to achieve non-basal texture during rolling, or at least, to reduce the intensity of the basal texture component. The reduction of the anisotropy caused by the basal texture is very important for subsequent forming processes. This project aims at optimizing the hot rolling process with special consideration of texture effects. The development of the model is carried out in close cooperation with the experimental work on magnesium alloy AZ31 .The experimental results are required for the determination of model parameters and for the verification of the model. Deformation-induced texture is described by the visco-plastic self-consistent (VPSC) model of Lebensohn and Tomé. The combination of deformation and recrystallization texture models is applied to hot compression tests on AZ31, and it is found, that the model describes the observed texture and hardening/softening behavior well. In some cases rotation recrystallization occurs in AZ31 which appears to be a possibility to reduce the undesired basal rolling texture.

Self Consistent

Due to crystallographic texture rolled magnesium sheets exhibit strongly anisotropic and asymmetric plastic behavior. Therefore the simulation of texture evolution during manufacturing is a prerequisite for the prediction of the material properties. For this purpose we coupled the viscoplastic self-consistent (VPSC) model with the commercial finite element code ABAQUS/Explicit®. As magnesium sheets are usually produced by hot rolling the VPSC model was supplemented with a simple model for recrystallization. This model is able to describe the softening behavior of the magnesium alloy AZ31 during hot compression and allows us to simulate the development of the typical basal texture during hot rolling of this alloy.
