中文摘要: 通过爆炸焊接技术制备的钛/铝复合板可兼具钛合金耐腐蚀性和铝合金低成本的优点。对钛/铝复合板爆炸焊接技术的研究进展进行介绍,论述了炸药种类、质量比R、基覆板间距及爆炸焊接窗口等主要工艺参数对钛/铝复合板组织和性能的影响;分析了影响钛/铝复合板结合界面的主要因素——金属间化合物种类、扩散层和界面波形;对钛/铝复合板硬度、抗剪切强度、抗拉强度及拉伸断口的研究进行了汇总分析。最后,指出了钛/铝复合板爆炸焊接工艺研究的重点发展方向。
Abstract:The Ti/Al clad plate prepared by explosive welding technology can have the advantages of titanium alloy corrosion resistance and aluminum alloy low cost. The research progress of explosive welding technology for Ti/Al clad plates was introduced, and discussed the effects of technological parameters such as explosive types, mass ratio R, base-to-flyer plate spacing and explosive welding window on the structure and performance of Ti/Al clad plates, and the main factors affecting the bonding interface of Ti/Al composite plate were analyzed, including the types of intermetallic compounds, diffusion layer and interface waveform of the interface in the Ti/Al clad plate. The studies on hardness, shear strength, tensile strength and tensile fracture of the Ti/Al clad plate were summarized. Finally, the development trend of explosive welding technology for Ti/Al clad plate is pointed out.
