Effects of a Pulsed Magnetic Treatment on the Fatigue of Low Carbon Steel
Magnetic pulses applied to low-carbon steel specimens following cyclic loading at stress amplitudes of 0.63 UTS and 0.74 UTS increased the subsequent fatigue life (and possibly the fatigue limit). It is proposed that the increased fatigue life is due to the influence of the external magnetic field o...

Summary: | Magnetic pulses applied to low-carbon steel specimens following cyclic loading at stress amplitudes of 0.63 UTS and 0.74 UTS increased the subsequent fatigue life (and possibly the fatigue limit). It is proposed that the increased fatigue life is due to the influence of the external magnetic field on domains and, in turn, on dislocation activity, the net result being a delay in crack initiation. |
