摘要：
In this second part of the paper, the implementation of the model presented in part I into the computer software 'MatCalc', is described. The new model is compared to the classical treatment of a moving boundary problem in phase transformations based on discrete composition profiles and good agreement is obtained. Selected examples demonstrate the model's potential for application to the evolution of the precipitate microstructure in multi-component systems where classical models frequently encounter difficulties due to the system's complexity.
