On the Kinetics of Precipitation in Alloys

Abstract

From the analysis of experiments on the precipitation of carbon in α-iron, it is suggested that the idea of chemical rate process is applicable to precipitation in alloys. A set of fundamental equations to describe the whole process of precipitation in alloys is postulated on the basis of nucleation theory and first order kinetic theory for the growth process. Approximate solutions were found, and good agreement with the experimental results was obtained. Some physical foundations and application of the theory were also discussed.
