Abstract

As is known, in domestic and world practice it has historically developed that in research and certification of alloys, high-cycle fatigue tests are carried out according to the «pure bending with rotation» loading conditions. Nowadays most scientist around the world give preference to high-cycle fatigue tests according to the «tension–compression» loading conditions. This article is about to assess the influence of the type of loading on high-cycle fatigue of nickel heat-resistant alloys GS6U, EI698 and heat-resistant titanium alloy VT8M-1.
