摘要：
The effect of microstructures on the fatigue behavior of V-added ferrite-pearlite type microalloyed steels was studied. It was found that fatigue cracks initiated from ferrite, and that crack initiation life had a great influence on fatigue limit. These results have indicated that the fatigue limit ratio could be improved by maximizing ferrite strength and optimizing ferrite volume fraction.
