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
