Effect of Additional Hydrogen Alloying on the Structure and the Phase Composition of a VTI-4 Intermetallic Alloy

Resumo

The formation of the structure and the phase composition of a heat-resistant titanium VTI-4 orthorhombic-intermetallic-based alloy is studied in the course of its alloying with hydrogen to different hydrogen contents. The laws of the changes in the phase composition of the hydrogen-containing alloy upon heating to different temperatures are determined. A portion of the VTI-4 alloy–hydrogen phase diagram under the conditions under study is constructed; it demonstrates the location of phase regions as a function of temperature and hydrogen content.
