摘要
结合耐石油腐蚀含铝钢在我国的应用情况及国内外焊接接头中碳迁移问题的最新研究进展,从碳活度角度探讨了含铝钢焊接接头中碳的扩散过程、脱/增碳层的产生机理,提出了抑制其产生的相应措施。
This paper talks about the domestic application of aluminium-containing steel and the latest research and development trend about the carbon migration of welded joint in home and abroad.From the point of the activity of carbon,the process of carbon diffusion and the reasons for formation of the carbon depleted/enriched zone were studied.Some relative measures were proposed so as to retard or suppress the carbon migration in the welded joint of the Al -containing steel.
