以特殊建筑屋顶用15Cr15Mo5Co14V钢材料为研究对象,分析了不同循环淬火和回火处理对实验钢组织和性能的影响。结果表明,淬火次数对实验钢硬度的影响不大,且其冲击韧度随着淬火次数的增加不断增加。
The roof of 15Cr15Mo5Co14V steel was used as the research object to analyze the effect of different quenching and tempering treatments on the microstructure and properties of the experimental steel. The results show that the number of quenching has little effect on the hardness of the experimental steel, and the impact toughness increases with the increase of the number of quenching.
