| Abstract Scope |
Zirconium and its alloys exhibit significant potential for orthopedic implants due to their excellent biocompatibility, corrosion resistance, and low magnetic susceptibility. However, the challenge of simultaneously enhancing yield strength while reducing elastic modulus has limited their clinical adoption. Here, Spinodal Zr–Nb and Zr–Nb–Ti alloys were designed using miscibility gaps in phase diagrams. Spinodal decomposition-induced heterogeneous strengthening improved yield strength and elastic admissible strain, reduced modulus, and significantly enhanced biomechanical compatibility. These spinodal Zr alloys showed superior wear/corrosion resistance, MRI compatibility, and biocompatibility compared to medical titanium alloys. Overall, spinodal decomposition is an effective strategy to optimize Zr alloys for orthopedic applications, advancing their translational potential in biomaterials. |
