| Abstract |
| We report on advanced β-titanium alloys having excellent biocompatibility without containing V or Al that has been known as a toxic element for human body, and on a low elastic modulus to be used in the fields of artificial joint and dental implant in the replacement of natural human bone. Ternary Ti-Nb-Si alloys consisting of biocompatible alloying elements have been produced to investigate the alloying effect on microstructure, elastic modulus and mechanical properties. On the basis of experimental results obtained, it is suggested that Si has an effective role to suppress the formation of ω-phase leading to reduction in elastic modulus. |
