Popis:	The paper is devoted to the experimental study of heat generation processes in various metallic materials under high-cycle loading with different values of asymmetry and amplitudes of cycles. Tests were performed on flat, smooth specimens subjected to cyclic stretching with increasing amplitude. Change in thermal radiation detected by an infrared detector, by the value of the thermal sensitivity of the device NETD was taken for the beginning of a metal sample self-heating. The stresses corresponding to the beginning of self-heating, are called critical. It has been established that Smith and Haigh diagrams of critical stresses of the onset of self-heating are similar to the same diagrams of ultimate fatigue stresses.
