A statistical approach has been applied to particle coarsening during liquid phase sintcring assuming direct particle coalescence as basic growth mechanism instead of Ostwald ripening. Tht coalescence process controlled by diffusion through the melt results in an increase of the average particle siz
The simulation technique based on the Potts model, originally applied to microstructural coarsening by Srolovitz et al. [Scripta metall. , 1983, 17, 2411 has been extended to study grain growth by Ostwald ripening in liquid phase sintered materials. The model, which makes no assumptions about solid
