中文摘要:研究了固溶处理对S31803双相钢板焊接接头微观组织的影响。结果表明:经固溶处理的焊缝和热影响区,晶内奥氏体析出变少,晶粒尺寸变小,同时奥氏体的形状由长条状变为圆状。
英文摘要:The effects of solid solution treatment on microstructure of welded joint of S31803 dual phase steel were studied. The results show that the precipitated austenite crystals of welded joint after solid solution treatment are fewer,the grains are smaller. And the shape of austenite changes from strip to roundness.
