Ag-Cu-Zn alloy for brazing TiC cermet/steel

The microstructures of the TiC cermet/steel joint brazed with Ag-31Cu-23Zn brazing alloy (1123 K, 20 min) and Ag-54Cu-33Zn brazing alloy (1123 K, 20/25 min) were investigated. When the amounts of Cu and Zn increase in the brazing alloy, there are not many Cu-base solid solution stripes and blocks but few Cu-base solid solution blocks occurred in the middle of the brazing alloy.
