Abstract
The effect of high-cycle fatigue loading (elastic deformation) of high-carbon steel (1.03 wt% C) on the behaviour of the tangential component of the magnetic induction vector of a specimen in the residual magnetization state has been studied. It has been found that the magnetic measurement technique allows both structural changes and cracks resulting from the fatigue degradation of high-carbon pearlitic steel to be recorded. The effect of cyclic loading in the low-cycle fatigue region (plastic deformation) on the variations in the coercive force and residual magnetic induction of annealed medium-carbon steel (0.45 wt% C) for the major and minor magnetic hysteresis loops has also been studied. The sensitivity of the magnetic characteristics to both large and small plastic strains accumulated during cyclic loading has been established.
