Abstract
Results from a diffusion-based model for transient liquid-phase sintering (TLPS) were used to predict the influence that the solute diffusivity (D), base-metal particle size (a), base-metal grain size (d), alloy partition coefficient (k), and the extent of solute saturation (X max/X o) had on the rate of isothermal solidification (where both X max/X o and k determine the initial liquid weight fraction in the system W A o). The solidification rate increases with an increase in D and a decrease in a, d, X o, and W A o, but decreases with an increase in k. Model predictions are close to, but slightly underestimate, results for the solidification rate measured in a Pb-Sn TLPS system.
