Low Rigidity Ti-Nb-Ta-X (X=Cr, Zr, Ag, In) Alloys with Improved Properties

Abstract:

The paper is focused on microstructure characterisation of five bulk metastable β-type Ti-based alloys, with improved mechanical properties, composed of non-toxic (bio inert) elements like: Nb, Ta, Cr, Zr, Ag, and In. These types of alloys designed in this study, are expected to have also higher corrosion resistance in biological media and good performance such as lower Young’s modulus of elasticity, greater strength, good workability, also in as cast state. However, high strength as well as low Young’s modulus is required for the implants subjected to cyclic loading under complicated stress conditions. Thus, the major aim is decreasing the Young’s modulus and increasing the tenacity of these alloys.
