摘要
对P91马氏体耐热钢焊接接头的冲击韧性进行分析,结果表明焊接时使用较低的焊接线能量有助于降低焊接接头组织的晶粒尺寸,减少马氏体板条块宽度,从而改善焊接接头的冲击韧性。
The impact toughness of P93 martensite heatresisting steel welded joint has been analysed. Results show that the lower welding wire energy used during the time of welding is helpful for reducting the grain size in the structure of welded joint, and for decreasing the width of martensite lath block, thereby, to improve the impact toughness of the welded joint.
