The Investigation of the Effect of Certain Factors on the Characteristics of Endurance of Heat-Resistant Alloys Used for the Manufacture of Turbine Blades,

Abstract

To clarify the reasons for the change in endurance, an analysis of the destruction of blade models was made during the transition of tests with a symmetrical cycle to an asymmetrical one; during the transition of tests in an air medium to tests in fuel compustion products; and during comparative tests of alitized and nonalitized models. The endurance characteristics obtained through the tests of the blade models reflect the effect of the shape, cycle asymmetry, working medium, thermal cycling, surface protection and test temperature on the endurance of heat-resistant alloys.
