WebJMAK theory. In the present paper, the modification of the classical JMAK approach by Rollett et al.13) to take into account the heterogeneity of recrystallization, was used to … The Avrami equation describes how solids transform from one phase to another at constant temperature. It can specifically describe the kinetics of crystallisation, can be applied generally to other changes of phase in materials, like chemical reaction rates, and can even be meaningful in analyses of ecological … Meer weergeven Transformations are often seen to follow a characteristic s-shaped, or sigmoidal, profile where the transformation rates are low at the beginning and the end of the transformation but rapid in between. The initial … Meer weergeven The simplest derivation of the Avrami equation makes a number of significant assumptions and simplifications: • Nucleation occurs randomly and homogeneously … Meer weergeven Originally, n was held to have an integer value between 1 and 4, which reflected the nature of the transformation in question. In the derivation above, for example, the value of 4 can be said to have contributions from three dimensions of growth and … Meer weergeven • IUPAC Compendium of Chemical Terminology 2nd ed.

First aspect is connected with tumor growth and cancer cells kinetics, which can be described by the sigmoidal curve. In this context the Avrami function was discussed as an alternative … Meer weergeven
