Kinetic treatment of glass formation: VII, Transient nucleation in nonisothermal crystallization during cooling

Numerical analysis was applied to isothermal crystallization kinetics and shown to yield crystallization vs time curves which compare very closely with curves calculated analytically with or without the inclusion of transient nucleation. Although the critical cooling rates associated with heterogeneous nucleation are large, the nucleation here takes place at relatively small undercoolings where the transient times are relatively small. The transient nucleation causes only a temporary delay in the overall crystallization, and its effect on the critical cooling rate is small. For part V, see Ceram. Abstr., 1982, 61 [5- 6] 61-02844A.
