| Abstract: | Cu/Al dissimilar metals were brazed with Zn-Al filler metals by torch-brazing technology,and the effects of Al on the spreadability and microstructure of Zn-Al filler metal were investigated separately.Moreover,the strength and microstructure of the brazed joint were also studied.Results indicate that the strength of the brazed joints achieves the optimum status when the Al content of filler metals is 15%.SEM and EDS are used to study the microstructure and phase constitution of the filler metals and brazed... |
