抄録

In order to investigate the effects of strain aging on the fatigue process of steel, the stressstrain hysteresis loops were measured through all stages of fatigue process by wire strain gauges 3 mm in length. Two kinds of killed steel have been used in the experiment; (e.g. 0.18% C and 0.12% C), all of them were sufficiently heat-treated to reduce the interstitial atoms C and N, thus varied the strain aging effects. The main results obtained are as follows : (1) The magnitudes of hysteresis loop decrease, being caused by the strain aging effects. (2) The materials tested under the strain aging effects are stronger than the materials free from the effects and the hysteresis energy accumlating until fatigue failure increase. (3) At the initial stage on the fatigue process, the maximum value of the strain aging effects appera.
