The Pd77.5Au6Si16.5 alloy was studied by means of a drop tube processing. Pd solid solution phase was found in smaller droplets (diameter D3Si was observed. The difference of free energy between underco-oled liquid and solid state, the activation energy for the formation of postcritical nuclei, tie nucleation rate and the speed of crystal growth were calculated as a function of temperature for Pd solid solution and PdsSi phases, these calculations led to time-temperature-transforma-tion curves which may be used to describe the experimental findings oa the kinetics of solidification of this alloy.
