采用Uodeholm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。

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-cycl...
