    摘要
  • 摘要: 采用脉冲钨极氩弧焊工艺,对含锡超纯铁素体不锈钢母材和焊缝的腐蚀性能进行研究.结果表明,焊缝能够获得与母材相当的耐腐蚀性能.含锡超纯铁素体不锈钢通过添加双稳定元素Ti和Nb,形成第二相Ti(C,N)和Nb(C,N),即使在焊接热循环的作用下,未熔解的Ti(C,N)和Nb(C,N)仍然起到细化铁素体晶粒和第二相强化的作用;添加微合金元素Sn,使得冷轧态的母材和焊接接头的耐腐蚀性能均得以提高,并且在焊接接头组织中的锡与Ti(C,N)和Nb(C,N)在晶界形成偏聚的竞争机制,从而得到耐腐蚀性能与母材相当的焊缝组织.
    Abstract: The corrosion properties of base metal and welding joint of ultra-pure ferritic stainless steel containing tin were studied by pulsed tungsten argon arc welding technique. The result showed that the corrosion properties of the weld was equal to that of the base mental. By adding Ti and Nb which formed the second phase Ti(C,N) and Nb(C,N), the unmelted Ti(C,N) and Nb(C,N) played a important role in refining ferritic grain and strengthening second phase during the welding thermal cycle. Simultaneous, the corrosion properties of the base metal and the weld were both improved by adding microalloy element of Sn, due to the segregation competitive mechanism between Sn with formed Ti(C,N) and Nb(C,N).
