Abstract The experimental data obtained at different times for various titanium alloys are collected in one place. Mechanical properties of VT1 – 0 alloy at normal temperature, creep and creep rupture properties of VT5 and VT6 alloys at 650 o C, secondary creep properties of VT1 – 0 alloy under complex stress at 550 o C have considered. The criterion for combining all these data was the large strains. © 2022 The Authors. Published by ELSEVIER B.V.

Keywords: Titanium alloy; hydrogen; circular hole; stress-strain dependence; high temperature; tension; torsion; complex stress; creep; rupture. 1. Introduction Titanium alloys have a low density, high strength and significant strength at high temperatures. The use of titanium alloys in aviation and rocket technology is most appropriate for the temperature range from 250 to 600 o C, when light aluminum alloys and magnesium alloys can no longer work, and steel and Nickel alloys are inferior to them in specific strength. Titanium interacts with oxygen especially intensively at temperatures above 700 o C Kolachev et al. (2001). Titanium dioxide is formed on the surface of titanium alloys at heated in an air environment. Titanium adsorbs large amounts of hydrogen at high temperatures. For example, titanium absorbs 32.000 cubic cm per 100 grams of hydrogen, and iron and aluminum 1.31 and 0.026 cubic cm at 600 o C and atmospheric pressure.
