Simple and precise description of the transformation kinetics and final structure of dual phase steels
Original language description
The kinetics of phase transformations is usually described by the Johnson-Mehl-Avrami-Kolmogorov (JMAK) equation. This approach is inaccurate when the conversion is only partial due to insufficient overheating, as the equilibrium fraction of the newly created phase for each temperature can then be calculated as a regression parameter. Moreover, the temperature dependence of the kinetic exponent in the JMAK equation is quite complicated and cannot be expressed by a simple general function. On the contrary, the equation of autoinhibition used for the description of austenitisation kinetics, instead of the JMAK equation, directly gives the equilibrium fraction at partial conversion, and, combined with the Arrhenius equation, it describes transformation kinetics at various temperatures independently of whether the conversion is complete or partial. This paper uses the equation of autoinhibition to describe the kinetics of austenite formation in dual phase steels.
