| 摘 要： | 将薄层钛合金板与铝合金板结合可以得到具有优异性能的钛/铝复合板，具有广阔的应用前景.采用爆炸焊接技术成功制备了TC1/1060/6061复合板，对2个界面的界面形貌和元素进行测试，分析夹层存在的优势；同时建立与试验条件一致的有限元模型，对界面状态和焊接过程进行分析，最后对复合板进行拉伸试验和剪切试验，验证界面结合质量. 结果表明，TC1/1060界面为直线型形貌，1060/6061界面为波状形貌，且每个波形都伴随着涡流区，TC1/1060界面处的元素扩散范围为4.38 μm，且没有检测到钛/铝金属间化合物的产生.数值模拟再现爆炸焊接过程中射流的形成，界面温度沿着界面形貌分布，界面压力在碰撞点处达到最大，且呈现出椭圆形分布，复合板具有较高的抗拉强度和剪切强度，满足结构使用需求.

| Abstract: | Titanium/aluminum composite plate with excellent performance can be obtained by combining thin layer titanium alloy plate with aluminum alloy plate, which has broad application prospects. TC1/1060/6061 composite plate was successfully prepared by explosive welding technology. The interface morphology and interface elements of the two interfaces were tested, and the advantages of 1060 interlayer were analyzed. At the same time, the finite element model consistent with the test conditions was established, and the interface state and welding process were analyzed. Finally, tensile test and shear test were carried out to verify the bonding quality of interface. The results show that the TC1/1060 interface has a linear morphology, and the 1060/6061 interface has a large wavy interface, and each wave is accompanied by the vortex region. The element diffusion range at the TC1/1060 interface is 4.38 μm, and no Ti/Al intermetallic compounds are detected. The numerical simulation reproduces the jetting formation in the process of explosive welding. The interface temperature is distributed along the interface morphology, and the interface pressure reaches the maximum at the collision point, showing an elliptic distribution. The composite plate has high tensile strength and shear strength, which can meet the requirements of structure use. |
