Research progress of heterogeneous structure magnesium alloys: A review

In recent years, a new class of metallic materials featuring heterogeneous structures has emerged. These materials consist of distinct soft and hard domains with significant differences in mechanical properties, allowing them to maintain high strength while offering superior ductility. Magnesium (Mg) alloys, renowned for their low density, high specific strength, exceptional vibration damping, and electromagnetic shielding properties, exhibit tremendous potential as lightweight and functional materials. Despite their advantageous properties, high-strength Mg alloys often suffer from limited ductility. However, the emergence of heterogeneous materials provides a fresh perspective for the development of Mg…
