Influence of Tempering Temperatures on Magnetoelastic Relaxation Behavior of 30KH13 Steel

摘要

Magnetoelastic tests of 30KH13 (30X13) steel were carried out under cyclic loadings. Similarly to the work [8], the article focuses on the property of magnetoelastic power relaxation of remanent magnetization. With the load amplitude increasing, complexes of power approximation coefficients reflect typical mechanical loads at various tempering temperatures. Qualitative changes in the behavior of these complexes begin with a tempering temperature of 530°C, which reflects changes in the structure of the material.
