Abstract
- Si<subscript>3</subscript>N<subscript>4</subscript> ceramics and 304 stainless steelwere joined by the Cu/Ag-Cu/Ti laminated fillermetal. Interfacialmicrostructure of brazed joint and effect of brazing temperature and thickness of Cu foil on mechanical properties were studied in this paper. Research results showed that the interfacial microstructure of the brazed joint might be 304 stainless steel/TiFe<subscript>2</subscript>/Ag-Cu eutectic + Cu(s,s)/Cu(s,s)/Cu(s,s) + Ag-Cu eutectic/Cu<subscript>3</subscript>Ti + TiN/Si<subscript>3</subscript>N<subscript>4</subscript> ceramics. With the increasing of the brazing temperature, four-point bending strength of the brazed joint initially increased, then decreased. The bending strength reached the maximum value of 53MPa at 1153K when the thickness of Cu foil was 500 µm. The bending strength reached the maximum value of 57MPa with 1mmthickness Cu interlayer under the brazing temperature of 1153 K. [ABSTRACT FROM AUTHOR]
