Quenching temperature influence on elastic and hardness behavior in a biocompatible Ti-based alloy

Abstract

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.
