Abstract

A set of AgCu/Cu-foam/AgCu/Ti multi-layered composite fillers was designed and employed to braze the Inconel 600 alloy and ZrB₂-SiC ceramic. Microstructures, formation mechanism and shear strengths of the joints were investigated in detail with and without the addition of Ti foil. The shear strengths of the brazed joints were improved substantially with the presence of Ti foils. A maximum gain of 150 % was reached from 77 MPa to 198 MPa after introducing the Ti foil and brazing the joint at a 1173 K for 15 min. The mechanical property enhancement is attributed to a newly formed TiC phase, release of residual stress, and barrier effect of Cu foam to inhibit formation of Ti-Ni intermetallic compounds.
