The Kinetic Description for Solid State Phase Transformation

Abstract

The progress of solid-state phase transformation can be subdivided into three overlapping mechanisms: nucleation, growth, and impingement. On the basis of an analytical phase transformation model, the maximum in the transformation rate of an isothermal solid-state transformation has been evaluated. Then, the mode of nucleation, growth and impingement, and the separate activation energies for nucleation and growth can be determined. Finally, application in the crystallization kinetics of amorphous alloy was described.
