| 摘 要： | 采用Ｕｅｄｅｈｏｌｍ法研究热作模具钢４Ｃｒ３Ｍｏ２ＮｉＶＮｂ和添加１．５％Ｍｎ后该钢的热疲劳性能。结果表明，添加１．５％Ｍｎ后，４Ｃｒ３Ｍｏ２ＮｉＶＮｂ钢的热疲劳抗力有所下降。试验结果同时表明，影响热作模具钢低周热疲劳的主要因素是钢的断裂韧性。

| Abstract: | The thermal fatigue behaviour of 4Cr3Mo2NiVNb steel without or with 1.5% Mn has been invetigated by Uddeholm methed,The results show that thermal fatigue resistance of 4Cr3Mo2NiVNb steel with 1.5%Mn decreases a lot.And fracture toughness is main factor that affects the low-cycle thermal fatigue of 4Cr3Mo2NiVNb steel. |

| Keywords: | thermal-fatigue fracture toughness grain size |
