摘要
近年来,许多研究都表明:与合金元素一样,氧对焊缝显微组织和韧性的影响亦十分显著。为此,本文较全面、深入地综述了氧在低合金钢焊缝中的行为,同时亦提出了作者对一些问题的看法。
Many researches in recent years show that the effects of oxygen on weld microstructure and toughness are very obvious. In this paper the oxygen behaviours in low alloy steel welds are further summarised and some viewpoints about these problems are also proposed.
