摘要: 对07Cr12NiMoVNb钢进行了常温和550℃旋转弯曲疲劳试验，结果表明，此钢不同晶粒度时疲劳断裂行为相近，室温疲劳强度与静强度关系符合奥金格经验公式，高温疲劳强度与静强度有关，但直线关系的系数不同于常温的，需重新总结。晶粒度大小影响疲劳强度，但室温表现的不明显，550℃表现为细晶钢疲劳强度高，这正好与蠕变行为相反，粗晶钢表现出较高的蠕变强度。

Abstract: Rotating-beam fatigue tests of 07Cr12NiMoVNb steel were carried out at room temperature and 550℃. The results indicated that the damage behavior of the steel samples with different grain size is similar. The relation between room temperature fatigue strength and ordinary tensile strength is in accordance to ojuger's experiential formula. High-temperature fatigue strength is related to ordinary tensile strength, but the linear coefficient is different from that of room temperature fatigue. Grain size has less influence on fatigue strength at room temperature. Yet at 550℃, the steel with fine grain exhibits higher fatigue strength which is contrary to creep behavior. For creep behavior, the steel with roase grain exhibits higher strength.
