| 中文摘要: |
| 采用多层复合法经后续热处理工艺制备了银铜锡中温钎料箔材，并对箔材的金相组织、熔化特性、力学性能、物相组成和钎焊性能进行分析表征。结果表明，采用多层复合法制备的银铜锡钎料箔材较铸态合金脆性明显改善，能够在室温下冷冲裁加工成特定尺寸的钎焊片；层状结构方式对多层复合银铜锡箔材的层状组织连续性影响较大，大变形轧制复合过程中会出现合金化、产生中间化合物，并伴随晶粒拉长。所得银铜锡钎料在铜、镍基材上润湿性和铺展性良好，钎焊铜、镍接头力学性能较好。 |
| 英文摘要: |
| Themultilayering method and subsequent heat treatment process were used to prepare multi- layer composite foils of silver-copper-tin medium temperature brazing filler. The microstructures, melting characteristics, mechanical properties, phase composition and brazing properties of the prepared foils were tested. The results showed that the brittleness of the foils was obviously improved, as illustrated by the fact that they could be blanked into a shape of certain thickness and specific size at room temperature. The continuity of the lamellar structure was obviously influenced by the layered arrangement, and the metals were alloyed during the composite process of large deformation rolling, producing intermediate compounds, which is accompanied by the elongation of the grains. Consequently, the multi-layer silver- copper-tin brazing filler metal displayed excellent a wetting and spreading ability on copper and nickel substrates, endowing the resulting brazed copper and nickel joints with preferable mechanical properties. |
