摘要
通过爆炸焊接工艺,采用玻璃微球敏化的铝蜂窝结构炸药,对Al_(0.1)CoCrFeNi高熵合金和1060 Al板进行了焊接。为了检测Al_(0.1)CoCrFeNi与Al的焊接特性,通过配备有能量色散光谱仪(EDS)的扫描电子显微镜(SEM)对焊接界面的形貌和组成进行了表征。结果表明,爆炸焊接技术是一种很好的高熵合金与铝连接的方法。在高速碰撞下得到的焊接试样界面熔化区中观察到了一些垂直于界面的裂纹,但并未向基体扩展。硬度测试结果表明爆炸焊接后高熵合金的整体硬度明显提高,而铝侧的硬度并无明显变化。腐蚀试验表明高熵合金具有良好的耐腐蚀性能。
The Al_(0.1)CoCrFeNi high-entropy alloy and 1060 Al plate were welded by explosive welding using aluminum honeycomb structure explosive sensitized by hollow glass microspheres. In order to test the welding characteristics of Al_(0.1)CoCrFeNi and Al, the morphology and composition of the welding interface were characterized by a scanning electron microscope(SEM) equipped with energy dispersive spectroscopy(EDS). The results show that explosive welding technology is a good method for joining high-entropy alloys with aluminum. Some cracks perpendicular to the interface are observed in the interfacial melting zone of the welded samples obtained under high-speed collision, but they do not extend to the substrate.The hardness test results show that the overall hardness of the high-entropy alloy increases significantly after explosive welding, while the hardness of the aluminum side does not change significantly. The corrosion test shows that the high entropy alloy has good corrosion resistance.
