In order to develop Ti based alloys with promising biocompatibility and matching mechanical response wit} human bone, TiTaNb alloys with 15, 23 and 30 mass% Ta are designed and systematically examined in terms 01 microstructural evolution and mechanical response. The Ti-30mass%Ta-10mass%Nb is demonstrated to be sa tisfactory with an elastic modulus similar to 60 GPa, hardness similar to 3.1 GPa, and strength similar to 1250 MPa. The evolution trenc of the resulting microstructure and phases as a function of Ta content and annealing temperature are established The relationship between the various phase amounts and alloy moduli is explored.
