Simulation of the Extrusion Texture of Magnesium Alloy AZ31 Using Crystal Plasticity Finite Element Method

By using Eulerian adaptive modeling approach, both the round extrusion and sheet extrusion of magnesium alloy AZ31 were simulated. Furthermore, the history strains of material point flowing through the Eulerian domain was extracted and used as the foundation for defining the boundary conditions in the crystal plasticity finite element (CPFE) modeling for the extrusion texture. By virtue of this modeling method, the realistic grain boundaries can be approximated by using a 3D polycrystal generator and the intra-granular interactions can be well described. Both of the simulated round extrusion and sheet extrusion textures of alloy AZ31 show reasonable agreement with experimental results.
