Metallographic and x-ray phase analyses are used for metal-matrix composites Al – B4C and (Al – 12% Si) – B4C with a volume fraction of 60% boron carbide prepared by infiltrating a pressed workpiece with metal under pressure. It is shown that with introduction of 1 to 4% Mg into a metal matrix composite porosity is reduced from 7 to 1%.
