Characteristic

This technology develops a metastable β titanium-rich medium-entropy alloy with excellent mechanical properties and biocompatibility for biomedical implant applications. The alloy exhibits high yield strength (>1100 MPa), low elastic modulus (<110 GPa), high elastic energy storage capability, and superior corrosion resistance in the as-cast condition without requiring additional heat treatment, thereby significantly reducing manufacturing cost and processing complexity. Compared with conventional implant materials such as 316L stainless steel, Co–Cr–Mo alloys, and Ti–6Al–4V alloys, the developed alloy effectively minimizes stress shielding effects and reduces the risk of metal ion release in the human body. Different alloy compositions can be tailored for specific orthopedic applications, including acetabular cups and femoral stems. Owing to its high strength, low modulus, wear resistance, and excellent elastic recovery capability, this technology demonstrates strong potential for next-generation orthopedic and biomedical implant materials.
