ABSTRACT

In this study, copper/steel composite tubes were produced by an underwater explosive welding process. Scanning electron microscopy, energy dispersive spectroscopy, electron backscatter diffraction and hardness tests were performed to analyse the microstructure and properties of the composite tubes. It was shown that by using an aqueous medium as a constraint, the inner tube cladding surface could be protected, shape distortion was reduced and the stringent requirements on the outer steel die were reduced. The results show that the copper/steel bond interface has a high-strength fine grain layer and that work hardening occurs near the interface after tube lamination.

Cu/Fe水下自约束爆炸焊管的实验研究

摘要

在这项研究中,铜/钢复合管是通过水下爆炸焊接工艺生产的。通过扫描电子显微镜、能量色散谱、电子背散射衍射和硬度测试对复合管的微观结构和性能进行了分析。结果表明,通过使用水性介质作为约束,可以保护内管包层表面,减少形状变形,降低对外钢模的严格要求。结果表明,铜/钢结合界面具有高强度细晶粒层,管层压后界面附近发生加工硬化。
