Abstract

A Monte Carlo simulation method for modeling sintering and grain growth of solid grains using a three dimensional lattice was studied to analyze an effect of anisotropic surface energy (γSV) of particles on the development of porous structures in sintered materials. The changes in porosity (fV), mean grain diameter (DS), fraction of connected pores (fV,C) and contiguity of the solid phase (C) were examined in cases with three different γSVsv relations and initial grain diameters (DS,0). Introducing anisotropic γSV brought an increase in fV and fS,V and an decrease in DS and C, and this tendency became more marked for fine D S,0. By this simulation study, the use of the particle with anisotropic γSV was considered to have an advantage to obtain fine and stable porous structures in sintered materials.
