An investigation was carried out to characterize the microstructure and bonding properties of the zirconium-carbon steel explosive clad. The microstructure and the composition of the clad were characterized using optical microscopy and scanning electron microscopy. Bonding properties were inspected by using bending and shearing tests. The examination results indicate that the R60702 and Cr70 plates were joined successfully without visible defects. The interface wave is symmetrical. There is no element diffusion across the interface of the clad plate. There are melt blocks at the interface. Bending and shearing test results indicate that the bonding properties of the clad meet the requirements of the ASTM B898 specification. And after shell rolling, no delamination appeared at the interface. Thus, it indicates that the clad plates have good bonding quality and meet the processing requirement.

用爆炸焊接表征锆碳钢复合材料的显微组织和结合性能

对锆碳钢炸药包层的微观结构和结合性能进行了研究。使用光学显微镜和扫描电子显微镜表征包层的微观结构和成分。通过使用弯曲和剪切测试来检查粘合性能。检测结果表明,R60702 和 Cr70 板成功接合,没有可见缺陷。界面波是对称的。在复合板的界面上没有元素扩散。界面处有熔块。弯曲和剪切试验结果表明,包层的结合性能符合ASTM B898规范的要求。轧制后,界面处未出现分层现象。因此,
