摘　　要：采用电磁脉冲焊接方法,进行T3纯铜与LF21防锈铝的异种材料焊接试验,并测试与分析了显微组织、物相组成、表面硬度和力学性能。结果表明,该方法可获得较高质量的焊接接头,接头抗拉强度为137 MPa,达到LF21防锈铝母材的110%,达到T3纯铜母材的51%;焊接接头由α-Al固溶体相、Cu相和Cu Al2相组成。Welding tests of T3 fine copper and rust-proof aluminum LF21 dissimilar materials are conducted by electromagnetic pulsed welding method,and the microstructure,phase composition,surface hardness and mechanical properties are tested and analyzed. The results show that this method can achieve high-quality welded joints,and the joint tensile strength is 137 MPa,reaehing 110% tensile strength of LF21 rust-proof aluminum base material, and 51% tensile strength of T3 copper base metal;welded joints comprise α-Al solid solution phase, Cu phase and CuAl2 phase.
