FIELD: metallurgy.
SUBSTANCE: method involves the filler backfill impregnating by the vacuum suction of the metal or alloy melt, which melting temperature is below the melting temperature of the filler. Provide the preparation of the filler backfill by mixing and compacting of the coarse and finely particles sodium chloride masses at the ratio, that is calculated according to the specified formula. The grain size of the finely divided sodium chloride is calculated from the specified formula, taking into account the grain size of the coarse divided sodium chloride and the axes angle of inclination in the artificial soil model, which is the function of porosity.
EFFECT: casting sporosity increase made from the metals and alloys, containing the aluminium or magnesium as the main element.
