ABSTRACT In this study, three series of Cu/CuCrZr composite plates were successfully achieved by explosive welding (EXW) method. The effect of the explosive rate and buffer plate on the microstructure and mechanical properties of bonding interface were investigated. In the bonding interface, no intermetallic or transition was formed. It was obvious that installing the buffer plate protected the composite plate from excessive ablation. With the increase of rate of explosive, the amplitude and wavelength of wave were increased. Some peninsular molten pockets were observed at the wavy interface adjacent to the wave crest of the three welds, the dimensions of which decreased with the decrease of explosive rate. Microhardness of bonding interface and outer face of plates were increased because of deformation that was originating from impact or reflection of the explosion pressure from the anvil. Microhardness and shear strength values were increased with the increase of explosive rate, while the values of clad plates with the buffer plate installed were more stable.

爆炸焊接制备的Cu/CuCrZr复合板的组织和力学性能

摘要 在这项研究中，三个系列的 Cu/CuCrZr 复合板通过爆炸焊接 (EXW) 方法成功实现。研究了爆炸速率和缓冲板对结合界面微观结构和力学性能的影响。在键合界面中，没有形成金属间化合物或过渡。很明显，安装缓冲板可以保护复合板免受过度烧蚀。随着爆率的增加，波的振幅和波长也增加。在三个焊缝波峰附近的波浪形界面处观察到一些半岛熔袋，其尺寸随着爆炸率的降低而减小。由于冲击或来自砧座的爆炸压力的反射引起的变形，使结合界面和板的外表面的显微硬度增加。显微硬度和剪切强度值随着爆炸率的增加而增加，而装有缓冲板的复合板的值更稳定。
