A method for estimating the grain-size and grain-aspect-ratio distributions in polycrystalline sintered bodies has been developed. We assume that grains are ellipsoids specified by three radii and that the radii distribution obeys to a probability-distribution function expressed with four distribution parameters. As a function of the four parameters, the area and the aspect-ratio histograms of the grain cross-sections of a sintered-body cross-section can be calculated by a Monte Carlo simulation method. The distribution parameter values are determined so that the calculated histograms conform to the observed ones by iterative calculation. We apply this analysis to the observed histograms about two kinds of alumina, obtained by using an image analyzer. The calculated histograms agree with the observed ones fairly well.
