| 摘 要： | 选用不同的降温速率，对1Cr5Mo钢进行退火处理，并测试其相关的组织变化及对力学性能的影响。结果表明，随着降温速率的降低，1Cr5Mo钢抗拉强度、屈服强度及布氏硬度逐渐降低，延伸率逐渐升高。降温速率为50℃／h时，试样各项力学性能指标较为优良，可为1Cr5Mo钢在实际工程应用中的热处理、热加工性能方面的基础研究提供一定的参考。

| Abstract: | By chooseing different annealing treatment cooling rate on 1 Cr5Mo steel,the related microstruc- ture change and its influence on mechanical properties were tested. The results showed that with the lower of the cooling rate,tensile strength,yield strength and brinell hardness of 1 Cr5Mo steel gradually reduce, elongation increased. Cooling rate of 50 ~C/h, the mechanical performance is relatively good. It may pro- vide a certain reference for 1Cr5Mo heat treatment and hot working performance in practical engineering applications of basic research. |
