| الوصف: | In the development of materials with desired properties, modelling of transformation kinetics is an important aspect. Ability of power Voronoi assisted simulation in predicting transformation kinetics is examined in this work. Initially, a mathematical model is derived incorporating the geometrical properties of power Voronoi diagram and classical nucleation theory. This is the governing equation for the power Voronoi assisted simulation. Transformed fractions at different temperatures are calculated using this equation. Simulation of microstructure evolution is carried out using power Voronoi diagram by giving nucleation rate and interface velocity as input. From the resultant geometry, it is possible to calculate the transformed fraction. The results are validated and verified using the available experimental results in literature. On comparison, it is evident that, transformed fraction can be predicted with less than 4% error using power Voronoi assisted simulation model with the derived governing equation. Thus, power Voronoi diagram can be used to simulate microstructure evolution during austenitisation with reasonably good accuracy in phase fraction. |
