Transformation kinetics of alloys 3 2 kinetic model one common approach to model the kinetics of non-isothermal phase transformation is to utilize the so called additivity rule [7, 8] the rule may be stated as follows: the temperature history (temperature vs time) is subdivided into a number of small type steps. The inverse kinetic problem is solved with the use of model-free friedman [6] methods and ozawa–flynn–wall [7,8] methods the model-free methods (friedman analysis, ozawa–flynn–wall analysis, evaluation according to astm e698) are applied to non-isothermal kinetic analysis when experimental data is represented as the set of.
