Enhancing functionalities of metallic materials by controlling phase stability for use in orthopedic implants

Abstract

This chapter aims to review the recent trends pertaining to the enhanced functionalities, including low Young’s modulus, self-tunable Young’s modulus, and low magnetic susceptibility, of titanium and zirconium alloys for use in orthopedic implants. These value-added functionalities can be realized by controlling the type of crystal structure and their lattice structure stabilities, which are related to the phase stability of titanium and zirconium alloys.
