Abstract
The results of fatigue tests of smooth cylindrical specimens with total deformation control under conditions of a symmetric cycle and elevated temperature are presented. The relationship between the values of the fatigue characteristics of the material with allowance for stresses, plastic deformation and the number of cycles to failure is considered. Comparison of deformation curves plotted from experimental data with deformation curves plotted by evaluative methods is presented.
