摘要：

Avrami's treatment of nucleation and growth kinetics considers that active nucleation sites are randomly distributed throughout the volume and that grains may impinge upon grains grown from other sites, causing growth to cease on the common interface. This treatment resulted in the well-known Avrami equation. As a result of the reassessment of these basic assumptions, an integral equation is proposed for the time-dependence evaluation of the transformed phase volume fraction in crystallization processes, instead of the Avrami equation. The proposed model fits very well the whole range of experimental data for NiZr2 and Te92Pb8 amorphous to crystalline transformation.
