Johnson-Mehl equation is written as d α /d t = k n t n1 (1 α ) where α is the degree of reaction, t time and n a constant. Use of this equation in kinetic analysis present problems because of the presence of a ' t ' term on the right hand side. The equation is not a ...
The contention of Sarkar and Ray that Johnson-Mehl-Avrami equation is not a true kinetic equation is disproved. It is shown that this equation can be expressed in the form of a standard kinetic equation. The results of the authors are only an approximation of Johnson-Mehl-Avrami kinetics when...

Equation 3 was solved by Sekimoto for I t =const, while Ben-Naim et al. derived a formal solution for arbitrary I t 21 . Below, we show that the solution of Ben-Naim et al. can also be obtained directly by applying Kolmogorov’s argument. In Fig. 3, we see a hole of size x ...

A temperature domain form of the standard Kolmogorov–Johnson–Mehl–Avrami (KJMA) equation is presented which can be used simulate phenomena such as phase transformation and recrystallization kinetics under non-isothermal conditions. This form of the KJMA equation relies on a parameterized temperature–...
