Self-Consistent Crystal Plasticity Modeling of Slip-Twin Interactions in Mg Alloys

Parsing the effect of slip-twin interactions on strain rate and thermal sensitivities Magnesium (Mg) alloys has been a challenging endeavor for scientists preoccupied with mechanical behavior hexagonal close-packed alloys, especially those great latent economic potential such as Mg. One main barriers is travail entailed in fitting various stress−strain behaviors at different temperatures, rates, loading directions applied to starting textures. Taking this task two Mg presenting textures levels were modeled using visco-plastic self-consistent (VPSC) code. A recently developed routine that captures dislocation transmutation by twinning interfaces hardening within twin lamellae was employed. While strong texture exemplified traditional rolled AZ31 weak represented ZEK100 alloy sheets. The model incorporated density based showed enhanced flexibility predicting complex sensitive textures’ response schemes.
