摘　　要：通过试验详细论述了不同锻造工艺对1Cr16Co5Ni2Mo1WVNbN钢的金相组织、室温拉伸冲击性能、450℃拉伸性能和持久性能的影响。从而得出结论锻造工艺对合金室温和450℃拉伸性能、持久寿命影响不大,变形量的增加有利于细化晶粒和一次碳化物NbC的尺寸减小,在1 120℃～1 160℃始锻温度、40%～60%变形量条件下锻造合金室温冲击韧性处于较高水平。该合金的最佳锻造工艺参数为:1 140℃下锻造,变形量50%左右。By experiment, this paper conducts a study on the influence of different forging technology on 1Crl6Co5Ni2MolWVNb steel＇s metallurgical structure, tensile property and impact property at room tem- perature ,tensile property and lasting performance at 450℃. A conclusion is drawn that forging technology has little influence on tensile property and creep rupture life at room temperature and 450℃ ;the increasing of the deformation amount is good for grain refining and the size reduction of the primary carbides NbC; at 1120℃-1160℃ starting forging temperature, the room temperature impact ductility of the forging alloy un- der the condition of 40% - 60% deformation amount is on a high level. The best forging technology param- eter for this alloy is： forging at 1140℃ ,deformation about 50%.
