铜合金复合钢一直被用于容器和其它装置,如热交换器,冷凝器,蒸发器以及粒子加速器等。Cu 90—Ni 10合金复合钢常用于海水蒸发器。本文阐述了用Ni做夹层的热轧复合钢的成形性和可焊性的试验结果,通过试验获得的结果如下;①复合钢经高温加热和剧烈地变形之后金属复层仍具有高的结合强度;②采用钨极隋性气体保护焊焊接时,不管是否使用铝青铜或蒙乃尔合金过渡层,弯曲试验不产生裂纹;③在铜上堆焊铜合金时,除蒙乃尔外,都能观察到如马修斯和薩维奇所报导的两种晶界的渗透;④为了制备焊接坡口,常常要剥去复层和在基体金属上开槽,但是,若开槽深度小于基体金属厚度的10％,则不降低接头强度。
Copper alloy clad steel has been used in containers and other devices such as heat exchangers, condensers, evaporators, and particle accelerators. Cu 90-Ni 10 alloy steel commonly used in seawater evaporator. In this paper, the formability and weldability of the hot-rolled composite steel sandwiching Ni are described. The results obtained through the experiments are as follows: ① The cladded steel still has high bonding strength after heated and deformed at high temperature ; ②With tungsten inert gas shielded welding, regardless of whether the use of aluminum bronze or Monel alloy transition layer, bending test does not produce cracks; ③ copper alloy surfacing on copper, except Monel can be observed Such as the penetration of the two grain boundaries reported by Matthews and Savage; ④ In order to prepare the weld groove, it is often necessary to strip the cladding and groove it in the base metal. However, if the depth of the groove is less than the thickness of the base metal 10%, then do not reduce the joint strength.
