IMPACT TOUGHNESS OF P91 STEEL WELDED JOINT
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。
Abstract
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.
