| الوصف: | Department of Materials Science and Engineering ; A Monte Carlo (MC) Potts model is proposed to study the sintering behaviors of two-phase systems, where a mutual transfer of solid and vapor phases occurs through various diffusion paths. In the proposed MC model, the diffusion paths and its rates are characterized and determined based on the categorization of the spin configurational changes occurring during the simulation. Three different cases, the pore densification through a bi-crystal grain boundary, the consolidation of three circular particles in two dimensions, and the consolidation of two contacting spherical particles in three dimensions, are considered to verify the proposed MC model. The relative contribution of different diffusion mechanisms to the sintering kinetics and microstructural evolution is investigated and compared with the initial- and final-stage sintering theories. It is found that the sintering kinetics are vastly influenced by boundary energy ratio between grain boundary and heterophase interface, and by the variation in the simulation temperature. ; close |
