Anisotropic segregation-driven texture weakening in a dilute Mg-Al-Ca alloy during isothermal annealing

Tailoring recrystallization via particle-stimulated nucleation (PSN) and pinning effects from secondary phase particles effectively weakens textures, which is still challenging for low-alloyed rare earth-free Mg alloys. Herein, the texture of a dilute cold-rolled Mg-2.2Al-0.33Ca (wt.%) alloy found to reduce with appearance transverse direction (TD) components during static recrystallization. The transition mainly attributed preferential growth TD-oriented recrystallized grains, resulting segregation Al Ca atoms on basal-oriented grain boundaries low misorientation angles. findings provide an in-depth understanding modification in
