Influence of cyclic loading parameters on fatigue characteristics of die steel

Abstract

Studying the fatigue characteristics of structural materials is a time-consuming process. The possibility of using high loading frequencies on the example of 5CrNiMn steel is presented in this paper. The results of studies of structurally sensitive characteristics are microhardness, electrical resistance and dislocation density. It is established that the nature of their change does not change with increasing loading frequency. Based on the obtained results the common nature of the accumulation of fatigue damage is assumed.
