Owing to the unique amorphous structure, glassy alloys exhibit high yield strength, low Young’s modulus, and high corrosion and fatigue resistance, which encourage their applications as biomaterials. Among the glassy alloys, Mg-based bulk metallic glasses (BMGs) are attractive as potential biodegradable implantation biomaterials. In this presentation, our findings regarding the syntheses and properties of Mg-based BMGs for potential biomedical applications will be reported. Novel Mg-based BMGs with improved glass-forming ability (GFA) and mechanical properties, suitable corrosion resistance and good biocompatibility were synthesized in Mg-Zn-Ca-Sr alloy system. It was found that the Sr-microalloying could effectively elevate the GFA and corrosion resistance of Mg-based BMGs. The mechanisms for the formation and properties of the Mg-based BMGs will also be discussed. The combination of the high GFA, superior specific strength, suitable and controllable corrosion behaviors, and good biocompatibility indicates the promising potential of the novel Mg-based BMGs to serve as biodegradable implant materials.
