摘　　要：金相分析表明,16MnDR+1Cr18Ni9钢埋弧焊焊缝金属组织为奥氏体（基体）+铁素体（少量）组成,并且在铁素体边缘有碳化物析出。焊缝中铁素体含量为8％～10％时,具有较高的抗裂性能。The metallography analysis shows that the structure of submerged arc weld metal for 16MnDR+ 1Crl8Ni9 steel joint is austenitc(basc) + fcrrile (small amount), and there is few precipitation of carbide. The content of fcrrite range about 8% -9%, the cracking resistance reaches higher level.
