通过爆炸焊接技术制备了含夹层的TC1/AA1060/AA6061复合材料,并对界面形貌和界面元素分布进行了研究。通过电子背散射衍射方法研究界面晶粒分布,并通过数值模拟得到的界面温度来解释晶粒分布。通过力学性能试验得到复合材料的拉伸和剪切力学性能。界面微观组织结构和力学性能的测试结果表明:TC1/AA1060/AA6061复合材料具有较好的焊接质量。两个界面形貌与数值模拟结果一致,数值模拟得到的界面温度可以解释界面和涡旋区域的晶粒分布。元素在TC1/AA1060界面的扩散宽度为12。3 μm,未检测到金属间化合物。在两个涡流区只检测到Al和O元素。此外,还在界面附近不同区域进行了纳米压痕试验,TC1/AA1060界面的纳米硬度介于两侧材料之间,而AA1060/AA6061界面的纳米硬度小于两侧材料。
Interface characteristics and mechanical properties of titanium/aluminum composites with an interlayer fabricated by explosive welding
In this work,the interface morphology and element distribution of the TC1/AA1060/AA6061 composite plate were studied.The grain information was investigated by electron backscattered diffraction and interface temperature was obtained by numerical simulation to explain the grain information.The experimental samples were tested by mechanical methods.The results show that the TC1/AA1060/AA6061 composite plate has better welding quality by observing interface morphology and testing mechanical properties.The morphology of the two interfaces was consistent with the simulation results,and the interface temperature can be explained by the grain information at interfaces and vortex regions.The diffusion width of elements at the TC1/AA1060 interface was 12.3 μm and no intermetallic compounds were detected;Only Al and O element were detected in two vortex regions.In addition,nanoindentation test was performed at different regions and the results were discussed.
