Modeling of {10-12}-{10-12} secondary twinning in pre-compressed Mg alloy AZ31

The deformation characteristics of rolled Mg alloy AZ31, which was previously compressed along the rolling direction and then re-compressed along the transverse direction, have been numerically investigated. Secondary/double twinning is allowed in the current EVPSC-TDT model, and {10-12}-{10-12} secondary twinning is found to play an important role in reproducing the experimental data. The deformation behavior of the pre-compressed materials …
