Although Monte Carlo (MC) simulations are widely used for understanding the microstructural evolution of sintering bodies, the models currently in use do not accommodate anisotropic material grain growth. This paper proposes and implements a two-dimensional algorithm to simulate the evolution of granular structure with anisotropic materials using a Potts MC model which incorporates the sintering mechanisms of grain growth, pore migration and vacancy annihilation. Limitations of this algorithm imposed by the underlying lattice structure are identified and solutions are proposed, implemented and tested.

Even though this ability to incorporate anisotropic grain growth in our meso-scale modeling does not provide a significant direct effect on the macroscopic

properties or deformation of sintered objects, it can allow us to investigate the granular development under several different situations to better understand some of the observed phenomena like patterning in sintered materials.
