摘要	The fatigue properties of high strength steel 42CrMoVNb with three fine grain sizes produced by different heat treatment procedures were studied. The experimental results illustrate that at 10(6)-10(7) cycles regime, there is no horizontal asymptote in fatigue S-N curves for smooth specimens, so the conventional fatigue limit disappears. SEM shows the fatigue crack initiation sites in smooth specimens are related closely to fatigue life, and most of the sites are at inclusions. From analyzing the experimental data, the critical size of inclusion and the most appropriate size of prior austenite, which should be controlled in practical production, are obtained.
