Abstract: Microstructure and shear strength of Ti(C,N)-based cermet/Cu–30Ag–3Ti filler metal/W9Mo3Cr4V steel joints were investigated after brazing in vacuum at 870, 910, and 950 ºC for 20 min, and 910 ºC for 10, 20, 30 and 40 min. The reaction layer of Cu–Ni–Ti solid solution between cermet and filler metal was difficult to form during brazing at 870 ºC, leading to very low shear strength of joints. During brazing at 910 ºC, Cu–Ni–Ti solid solution was formed between cermet and filler metal, and it became thick with the increase of holding time. Shear strength of joints reached a peak value for 30 min.
