The rearrangement process during liquid phase sintering is generally accepted as being
driven by the capillary forces between solid grains embedded in liquid. This process
assumes that if there is good wetting between liquid and solid phases, solid grains will
rearrange themselves under the action of surface tension forces, producing more stable
packing. This paper outlines a computer-based method for three-dimensional computer
simulation of rearrangement during liquid phase sintering. The theoretical models dealing
with the fundamental interaction forces that exist between grains attached by liquid
bridges will be outlined and the development from these pair-wise interactions to multigrain
models will be described.
