Torsion tests were performed on AA6082 samples to investigate their flow softening behavior and to determine optimum process conditions. Based on the experimental data and dynamic materials model, high strain processing maps were established which demonstrate the constitutive relationships among temperature, strain rate, strain and stress. The flow curves exhibited..... More
