Achieving high strength and low Young's modulus by controlling the beta stabilizers content in Ti-Nb-(Ta)-(Zr)-O alloys

Abstract

Metastable beta titanium alloys have been studied for over two decades to explore their applicability in production of joint implants. The aim is to suppress the Young's modulus to a value close to that of bone (10 - 30 GPa).

At the same time, strength requirements for the construction of the implant should be met, e.g. yield strength of at least 900 MPa as in currently used Ti-6Al-4V alloy.
