The simplest possible non-isothermal generalization of the phenomenological isothermal rate equation has been investigated. Its solution, the transformed fraction, C, is a functional of the temperature-time relation, T(t). Previous works, based on the existence of a function-type solution, C(T,t), suggest a way of generalization which is meaningless in the case of a functional solution. A difference is predicted by the function-type description between the kinetic parameters under isothermal and dynamic conditions which is in contradiction with our experimental results on the crystallization of Fe75B25 metallic glass.
