Methods for studying the cross-sectional distribution of density and strain in metal powder compacts are reviewed. A method for studying strain and density distribution during powder compaction is proposed. It involves layer-by-layer filling of the mold cavity with powders of identical composition, shape, and particle size but of different colors, (compaction, cutting of the compact, scanning the cutting plane, and digitization of its image. The application of the method proposed and the results of the digital processing of the image are presented.
