Abstract：
Joining immiscible materials such as copper and stainless steel together is a significant concern due to distinct mechanical and metallurgical properties across the joint line, such as melting points, the coefficient of linear thermal expansion, and thermal conductivity. The joint properties of copper to stainless steel welds are in great demand for various mechanical components of the international thermonuclear experimental reactor, ultra-high vacuum system, plan wave linear-accelerator or linac structure, and heat exchanger. These dissimilar-metals joints offer excellent flexibility in design and production, leading to a robust structure for many cutting-edge applications. Hence, the present article reviews the copper to stainless steel joining mechanism under different solid-state processing conditions. The present understanding says that defect-free strong joints between the dissimilar metals are systematically possible. Apart from this understanding, the authors have identified and highlighted the gaps in the research exploration to date. Moreover, a sustainable methodology to achieve a desirable weld of copper to stainless steel depends on favorable processing conditions.
摘要：
将不混溶的材料，如铜和不锈钢连接在一起是一个重要的问题，由于不同的机械和冶金性能的连接线，如熔点，线性热膨胀系数，和导热性。国际热核实验堆的各种机械部件对铜与不锈钢焊缝的接头性能要求很高,超高真空系统,计划波直线加速器或直线加速器结构，和热交换器。这些异种金属接头在设计和生产方面具有出色的灵活性，导致一个强大的结构为许多尖端的应用。因此，本文综述了不同固态加工条件下铜与不锈钢的连接机理。目前的理解表明，不同金属之间无缺陷的坚固接头是可能的。除了这种理解,作者发现并强调了迄今为止研究探索中的差距.此外，一个可持续的方法来实现一个理想的焊接铜不锈钢取决于有利的加工条件。
