摘要
比较了Ｎｂ－Ｖ、Ｎｂ－Ｔｉ两种微合金钢在高温下抗奥氏体晶粒长大的能力，以及经受高温焊接热循环后，两种钢的冲击韧性。试验结果表明，Ｎｂ－Ｔｉ钢焊接热影响区比Ｎｂ－Ｖ钢具有更高的冲击韧性。
In this paper the ability of Nb-V and Nb-Ti microalloyed steels to resist austenite grain growth and the impact toughness of the two steels after high temperature welding thermal cycle are compared. Research results indicate that impact toughness of welding heat affected zone of Nb-Ti steel is higher than that of Nb-V steel.
