Owing to the unique amorphous structure, metallic glasses exhibit high yield strength, low Young’s modulus and high corrosion resistance, which encourage their applications as biomaterials for implants. Among the bulk metallic glasses (BMGs), Ti-based ones are the most attractive for application as long-term implantation biomaterials. In this presentation, our findings regarding the syntheses and properties of Ni-free Ti-based BMGs for potential biomedical applications will be reported. We have successfully synthesized novel Ti-Cu-Zr-Fe-Sn-Si-Ag(Sc) system BMGs with superior glass-forming ability (GFA). The Ti-based BMGs exhibit higher specific strength, superior bio-corrosion resistance and good cytocompatibility in comparison with the Ti-6Al-4V alloy. It was discovered that the addition of Ag and Sc could significantly improve the GFA and some properties of the Ti-based BMGs, and the related mechanisms will be discussed. The integration of high GFA, high corrosion resistance, and good mechanical properties and biocompatibility demonstrates the potential of the Ti-based BMGs as biomaterials.
