Fabrication processes, properties, and applications of Ti-15Mo alloy

As a representative β-phase titanium (β-Ti) alloy, Ti-15Mo exhibits versatility for applications in biomedical and engineering fields owing to its multiscale performance advantages. In biomedical applications, its elastic modulus (60-80 GPa) closely matches that of cortical bone, while its tensile strength (∼900 MPa) and osseointegration capabilities make it ideal for orthopedic and dental implants. Furthermore, its excellent biocompatibility and corrosion resistance can minimize post-implant inflammatory responses and long-term degradation, thereby reinforcing its suitability for medical implant applications. This review highlights recent developments in the fabrication and surface modification of Ti-15Mo and emphasizes its performance advantages. Nevertheless, challenges persist, including complex processing, high cost, metastable β-phase control, and surface functionalization. Future research should aim to develop cost-efficient alloys, optimize manufacturing, and advance multifunctional surface modification techniques to expand their application potential.
