| 摘 要： | 研究了钎焊温度对非晶钎料微观组织转变的的影响,利用EPMA、XRD等方法分析在升温过程中钎料的组织转变及元素扩散情况,并与普通晶态钎料进行对比研究.结果表明:由于凝固方式的不同,非晶钎料在晶化后为完全共晶组织,且晶粒细小均匀,这有利于提高钎焊接头的性能.

| Abstract: | The amorphous fillers with components Cu68.5Ni15.7Sn9.3P6.5 (wt%) are brazed with copper by vacuum brazing. The microstructure transformation during ramp-up are studied by means of XRD, EPMA and DSC. The results show that the crystallstructures of amorphous filler are fully eutectic organizations with small and uniform grains, as a result, its joint mechanical properties are enhanced by different solidification ways |

| Keywords: | amorphous Cu-P filler metal microstructure transformation brazing |
