摘　　要：观察焊缝的金相组织,测定力学性能及其冲击功,利用Boltzmann函数确定韧脆转变温度,得出2.25Cr-1Mo-0.25V钢焊缝经阶梯冷却后,抗回火脆化的性能良好。The metallographic structure, the mechanical property and impact energy of weld were examined and measured. The ductile-brittle transition temperature was determined by Boltzmann Function. By step cooling tests, 2.25Cr-1Mo-0.25V steel weld has the perfect resisting temper embrittlemelat capability.

关 键 词：2.25CR-1MO-0.25V钢 焊缝 回火脆性
