Ti-Zr-Nb system with diffusion multiple was manufactured, then annealed at 1273 K for 1800 h, and water quenched to room temperature. Combining nano-indentation and electron probe micro-analyze (EPMA), the elastic modulus, hardness as well as composition at each point of the diffusion multiple were determined. Based on the experimental data, the composition-hardness-elastic modulus database of the Ti-Zr-Nb alloys is obtained. The results show that the elastic modulus and hardness depend strongly on Zr and Nb content. Ti-41Zr-10Nb has a relative lower elastic modulus, and a relative larger hardness, which is promising candidates as metallic biomaterials for application. The high-efficiency combinatorial approach has demonstrated to be an effective tool in accelerating the metallic biomaterials research and discovery.
