Interfacial microstructure and mechanical strength of ferritic stainless steel and silicated graphite joints bonded with Cu/Ni composite interlayers

Cu/Ni composite interlayers were used to bond 000Cr30Mo2/silicated graphite samples at 1100–1150 °C. Brittle Cr7C3 in the reaction layer was restricted by the addition of Cu. The shear strength increased with Cu interlayer thickness.
