Justification of the Titanium-Based Alloy Chemical Composition to Provide High Hardness

Abstract

The article presents comparative data on the properties of different materials used for the manufacture of bearings. The influence of the chemical composition and structure of titanium-based alloys on the change in hardness during various types of processing is studied. It is shown that the most promising for the manufacture of bearings are high-alloyed titanium alloys of the VT22 type, in which the hardening heat treatment allows to obtain a high hardness.
