N2 - Fusion welding or brazing of refractory metals is, in general, not desirable due to the recrystallized, brittle microstructure produced in the joint. In view of this, it is preferable to reduce the bonding temperature by conducting solid-state diffusion bonding at a low temperature to prevent recrystallization. It is demonstrated that a number of refractory metals systems, e. g. , TZM-Mo (Mo-Ti-Zr) to TZM-Mo, TZM-Mo to C103 (89Nb-10Hf-lTi) and W-25Re to W-25Re, can be joined together by solid-state diffusion bonding at temperatures below that for the recrystallization of the parent metals by using either Nb, Ta, Ti, or Ni as interleaf materials. Parameters affecting the quality of the joint, particularly the surface preparation prior to bonding, are discussed. This particular type of joint has immediate applications in many aerospace structures.
