Abstract
Impact Fatigue and usual fatigue experimenls were carried out by using carbon steel and high-manganese steel specimens. Impact fatigue lives for crack initiation at the notch roots and for fracture were unfavorable compared with usual fatigue. Although crack propagating periods under pulsated and repeated loadings were comparable in the case of usual fatigue, difference of such a loading condition influenced on both crack initiation and propagation period in the case of impact fatigue. According to the result of measuring of the dislocation density in terms of the Xray method, plastic zone size near a crack was estimated to be small in the case of impact fatigue compared with that of usual fatigue. Similar results were obtained for high manganese steel, and the influence of rolling direction was not observed.
