A crystal plasticity investigation of grain size-texture interaction in magnesium alloys

This work investigates the microstructure-property linkages in magnesium (Mg) with an emphasis on understanding interaction effects between grain size, texture, and loading orientation. A single crystal plasticity framework endowed experimentally informed micro Hall-Petch type relations for activation thresholds slip twinning is adopted to resolve polycrystalline microstructures over a broad texture-grain size space. The macroscopic trends from simulations corroborate experiments. synergistic of microstructural engineering micromechanical characteristics are mapped, which reveal their role emergent behaviors. predict reduced extension refinement even though coefficient smaller than that non-basal modes. While textural weakening generally reduce net plastic anisotropy tension-compression asymmetry, degree these behaviors tempered depends results offer preliminary insight into roles texture may play damage behavior engineered Mg microstructures.
