Simulation of texture and crystallite microstrain development during compression and tension of an Al alloy and comparison to experimental results

Cold compression textures, tension textures and crystallite microstrains of an AlMg3 aluminum wrought alloy were simulated using the Taylor-Bishop-Hil l theory and an elastic unloading model. The results of the simulations are compared to inverse pole figures determined by X-ray diffraction and epsil on (phi psi) vs sin(2)psi -curves determined using synchrotron radiation. I t is shown that the texture evolution has a strong influence on the crystal lite microstrains and produces nonlinear microstrain curves, which can be i nterpreted and evaluated using the results of the simulations.
