説明
Full three-dimensional finite volume method (FVM) simulation was carried out for two types of Mg alloys. The load-stroke curve, effective strain, effective stress, and strain rate were obtained during the virtual superplastic forging process. The above results for fine-grained Mg alloy showed localized flow behavior because of the change in dominant deformation mechanism at a high strain rate above ca. 0.8 s−1. However, RS P/M Mg–Zn–Y alloy showed relatively uniform metal flow at the same strain rate.
