摘要
研究了不同钒含量的 4 2CrMo钢的缺口拉伸延迟断裂性能。试验结果表明 ,钢中加入适量的V能够改善高强度钢的耐延迟断裂性能 ,并对其作用机制进行了探讨。
Effect of vanadium microalloying on delayed fracture resistance of 42CrMo steel was investigated using notched tensile specimen in pH3 5 Walpole solution.It′s showed that suitable amount of vanadium can significantly improve the delayed fracture resistance of high strength steel.The reason of this improvement was discussed.
