Elasticity modulus and hardness changes in deformed semifinished rods manufactured of biocompatible Ti-6Al-7Nb alloy under quenching from the temperatures in a range of 500-1050°C have been studied by means of indentation. The elasticity modulus and Vickers hardness have been shown to vary from 95 to 115 GPa and from 330 to 520 HV respectively depending on the quenching temperature. Relationship between the elastic and hardness behavior and the alloy phase composition has been found.

This article provides a brief overview of the metallic materials used as implants in orthopedics, the alloying system and a complex of the physical-mechanical properties for metallic materials certified for medical use, as well as the advantages and drawbacks of using metallic materials as implants. Approaches to improve the quality of an implant made of metallic materials are noted.
