Description
Summary:Scanning electron microscopy and x-ray phase analysis results are presented for powders prepared by chemical dispersion of alloy Al–Mg (20 wt.%) and specimens of porous ceramic materials made from these powders. Different powder fractions are obtained during chemical dispersion of aluminum-magnesium alloy. A powder fraction finer than 50 μm is selected for study. Ceramic specimens are prepared by semidry compaction. Features of phase composition and structure of heat-treated powders and ceramic prepared with a high magnesium content in the original alloy are described.
