On the Effect of Liquid-State Diffusion on Isothermal Solidification Completion Time During Transient Liquid-Phase Bonding of Dissimilar Materials

  • O. A. Ojo

A study of transient liquid-phase bonding (TLPB) of dissimilar materials consisting of a nickel-based superalloy and a cobalt material is performed. In contrast to the assumption that rapid atomic diffusion in the liquid would reduce the processing time, tf, required to completely eliminate the liquid phase from the joint region through diffusional solidification, the occurrence of liquid-state diffusion significantly prolonged the processing time tf. This finding is crucially important to the TLPB of dissimilar materials.
