For planning of thermal fatigue tests of materials and comprehensive analysis of their results, it is proposed to use the thermal cyclic test maps (TC-maps) that allow tracing the strain development in a thermal cycle. TC-maps illustrate the diagrams of the temperature-dependent elastic strain, which corresponds to the yield strength of the material, and the free strain variation under constraint conditions. This paper presents the procedure of thermal cycle test map compiling for some materials and their physical as well as mechanical properties. The useful information obtained from the TC-maps is exemplified by some heat-resistant alloys employed for the production of gas-turbine engine blades. [ABSTRACT FROM AUTHOR]
