Abstract Scope |
A novel exploration of the relationship between coarsening annealing and the moving boundary problem approach is attempted, with a particular emphasis on diffusion. Stefan's solution, and non-integer exponents in the power law of interface versus time are simulated. The research delves into the complex dynamics of phase transformations, specifically the process of coarsening annealing, in effectively modeling the moving boundary problem. The role of diffusion in these transformations is explored, elucidating how atomic mobility influences the coarsening process. A significant focus of this study is the investigation of non-integer exponents in the power law of interface versus time. This aspect challenges traditional models and provides a more nuanced understanding of phase transformations. It is demonstrated through the enthalpy formulation of the MBP that the interface aligns closely with the Stefan solution. However, non-integer exponents can accurately model interfacial dynamics over larger time, offering new insights into the coarsening process. |
