摘要: A diffusion brazing of aluminium alloy A6061 was preformed using a Ag-28Cu insert to conduct eutectic brazing. Interface behaviors the brazed joints were observed after at 450-560°C. The tensile property also examined. During Al6061 alloys with insert, melts formed by reaction between and insert. It found that layers composed two phases interface EPMA analysis revealed in consist Ag-rich phase Cu-rich phase. strength 560°C for 30min 160 MPa.
