Abstract

The effect of various modes and technological parameters of hardening heat treatment on mechanical properties and structure of sheets from an experimental composition of a high-strength metastable β-titanium alloy doped with rare-earth element yttrium have been studied.

It has been shown the possibility of wide variation within parameters and morphology of structural constituents of the experimental alloy composition. The experimental alloy can be effectively strengthened both by conventional heat treatment and low-temperature thermo-mechanical treatment (LTMT). Long-term low-temperature ageing makes it possible to provide high level of strength characteristics with satisfactory values of elongation and impact toughness.
