摘要：
A study on the interfacial activity behavior of flux during aluminium brazing has been madeby using metallography,SEM and electron prob techniques.The results show that the activity,of a flux is caused by the wetting of base metal with the liquid heavy metal reduced from theflux,thus,some regions of liquid alloy created,at which no aluminium oxide film covers on thesurfaces.The reduced metal drops are finally trapped in the fillet.The size of the metal dropsincreases with the decrease of brazing temperature.
