Kinetics and Thermodynamic Transformation of a Special S.G. Cast Iron

Abstract

The paper contains a study about the kinetics and thermodynamics transformation of a S.G. Cast Iron during the isothermal heat treatment. With the help of Johnson-Mehl and Arrhenius equations, there were described the activation energy “Q”, rate coefficients dependent on temperature “k”, exponent of reaction “n” and a constant dependent on frequency “A”.
