Abstract

The article presents and summarizes the test results of the mechanical properties of material of industrial sheets with a thickness of 2,0 mm made of heat-resistant titanium alloy VT41. The results of tensile tests, low- and high-cycle fatigue tests of flat samples are presented as well as the results of tensile testing of samples with a corset shape of the working part at different loading speeds. On the base of tests results a stress-cycles to failure curve is  constructed in the areas of static, re-static, low-cycle and classical high-cycle destruction.
