    摘要
  • 摘要: 分析了夹杂物对Ag-Cu-Zn基钎料BAg40CuZn(Mn,Ni,Co)组织与性能的影响. 在大气条件下熔炼,BAg40CuZn钎料中的Mn,Co元素易形成Mn2O3,Co3O4,MnN等夹杂物. 由于氧化物和氮化物的硬度高于BAg40CuZn钎料基体的硬度,且自身的变形能力差,降低了钎料的塑性变形能力. 在塑性加工前期,拉拔力较大,变形过程中产生的挤压力使夹杂物发生碎裂,并沿拉伸变形方向分布. 在塑性加工后期,拉拔力变小,在变形过程中产生的挤压力不足以使夹杂物发生碎裂,造成局部应力增大,当其超过钎料基体的抗拉强度后,在夹杂物周围形成裂纹源并扩展,导致钎料在变形过程中发生断裂.
    Abstract: The influence of the inclusion formed in solidification process on the microstructure and mechanical properties of BAg40CuZn(Mn, Ni, Co) Ag-based filler metal was investigated. When the filler metal was melted under air condition, some inclusions (Mn2O3, Co3O4, MnN) were formed owing to the reaction between element Mn and Co with oxygen and nitrogen in air. The plastic deformation ability of the BAg40CuZn filler metal was decreased because of the higher hardness and lower deformability of inclusions. At the earlier stage of the deformation, the extrusion force is sufficient to break the inclusion in matrix. The broken inclusions distributed along the direction of extruding. At the later stage of deformation, the extrusion force was decreased that is not sufficient to break the small inclusions. These inclusions decreased the stress bearing area of the filler metal, resulting in stress concentration nearby. When the stress is greater than the yield limit of the matrix, crack would initiate around the inclusion. With the increase of stress, the crack propagates that causes the damage of filler metal finally.
