NiTi形状记忆合金具有优良的形状记忆效应、超弹性、生物相容性、抗阻尼性能、抗腐蚀性能及综合力学性能，为了扩展其在智能开发中的应用，NiTi合金与其他综合性能良好的结构材料的连接备受关注。采用电磁脉冲焊连接NiTi/6061铝合金，利用光学显微镜（OM）以及扫描电镜（SEM）分析了不同热处理状态（T6态和完全退火态）和放电能量对母材及焊接接头微观组织的影响，利用DSC分析不同放电能量下NiTi合金的形状记忆效应。结果表明，完全退火处理有利于6061铝合金与NiTi的连接，电磁脉冲焊界面区厚度小于5 μm，对NiTi合金的形状记忆效应影响较小。
With excellent shape memory effect (SME) and super-elasticity (SE), biological compatibility, damping resistance, corrosion resistance and comprehensive mechanical properties, NiTi shape memory alloys (SMA) was widely used in the fields of aerospace, artificial intelligence and biomedicine, etc. In order to expand its application in intelligent development, dissimilar welding of NiTi alloy and other structural materials (such as Al6061 aluminum alloy, steel, Ti6Al4V alloy) has attracted much attention. In this study, NiTi/6061 aluminum alloy was welded by magnetic pulse welding (MPW). The microstructural features of base metal and welded joint at different heat treatment states (T6 state and fully annealed state) and discharge energy were investigated by optical microscope (OM) and scanning electron microscope (SEM). Martensitic transformation properties of NiTi before and after welding under different discharge energy was analyzed by DSC. The fully annealing treatment was beneficial to the joining between 6061 aluminum alloy and NiTi, and the thickness of the interface zone is less than 5 μm. The MPW has little effect on the shape memory effect of NiTi alloy.
