Abstract
In order to develop Ti based alloys with promising biocompatibility and matching mechanical response with human bone, TiTaNb alloys with 15, 23 and 30 mass% Ta are designed and systematically examined in terms of microstructural evolution and mechanical response. The Ti-30mass%Ta-10mass%Nb is demonstrated to be satisfactory with an elastic modulus ~60 GPa, hardness ~3.1 GPa, and strength ~1250 MPa. The evolution trend 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.
