Abstract

Based on AgCuNiMn alloy, Ni/Cu/AgCuNiMn high-Ni solder was designed by in-situ synthesis. The WC-6Co/In718 joint was prepared by vacuum brazing at 950 °C for 10 min. The effect of metal foil on the filler metal filling ability, microstructure and mechanical properties of the joint was studied. The microstructure evolution and strengthening mechanism of the joint brazed with Ni/Cu/AgCuNiMn solder were analysed. The results showed that Ni element mainly plays a solution-strengthening role on the joint, and improve the interface bonding strength and the strength of Ag (s, s) distributed in the centre of the brazed joint, which increased the average tensile strength by 32.4% (from 426.5 to 564.7 MPa).

原位合成Ni/Cu/AgCuNiMn钎料钎焊WC-6Co/In718的研究

基于AgCuNiMn合金，采用原位合成方法设计了Ni/Cu/AgCuNiMn高镍钎料。采用950℃真空钎焊10 min制备WC-6Co/In718接头。研究了金属箔对钎料填充能力、接头组织和力学性能的影响。分析了Ni/Cu/AgCuNiMn钎料钎焊接头的显微组织演变及强化机理。结果表明:Ni元素在钎焊接头上主要起固溶强化作用，提高了界面结合强度和分布在钎焊接头中心的Ag (s, s)的强度，使钎焊接头的平均抗拉强度从426.5提高到564.7 MPa，提高了32.4%;
