Summary

Joining of pressureless-sintered SiC using nickel and active metal (or hydride) powder mixtures was studied using a fracture shear strength test. The interlayers of these joints were characterized using XRD and SEM-EDX methods. Maximum shear strengths over 100 MPa were obtained in those joints. Characterization of the interlayers using the above-described analytical methods revealed that the interlayers have a cermet-like microstructure, which consists of ZrC (or TiC) and nickel silicide (or Ni-Ti silicide).
