The influence of the loading frequency on the endurance limit, durability and cyclic strength of metals and alloys in the high frequency range depends on several factors: stress level, voltage change, loading method, material structure. With increasing speeds and power of engines and power-driven vehicles, the fatigue strength of parts and components is becoming increasingly important. During operation, parts are exposed to high-frequency cyclic loading, and their service life and reliable operation are determined by fatigue strength in most cases, therefore, it is necessary to conduct fatigue tests in a wide range of loading frequencies. In the general case, the frequency of application of the load ambiguously affects the material’s resistance to fatigue; therefore, different materials in different areas of fatigue failure have differences in their response to a change in the loading frequency.
