In this article an experiment is described which is included into a course in materials science and allows for better understanding of a nature of sintering. It is a fusion of a computer simulation and a physical experiment – both performed in model systems. Part I of the experiment concerns microstructure of powders. Packing density and coordination numbers of the grains in the sintered powder are analysed with application of computer simulation. In part II of the exercise, the kinetics of the sintering of glass grains is measured via microstructure-evolution observations. The results may be used to discuss the mass transport mechanism.

The Relationship

A computer simulation coupled with fabrication temperature for the sintering process of two-phase ceramic tool materials has been developed using a two-dimensional hexagon lattice model mapped from the realistic microstructure. The relationship between fabrication temperature and microstructure evolution is proposed. The mean grain sizes of simulated microstructures by Monte Carlo Potts model integrated with fabrication temperature increase with an increase in fabrication temperature, which is consistent with the experiment results.
