FIELD: metallurgy.
SUBSTANCE: molten aluminium is prepared and overheated above its liquidus temperature. The molten metal is filled into the casting mould heated to the same temperature. Into the casting mould the sheets from alloys of transitional metals are pre-placed and fill up with granules from water-soluble salts. The sheets are pre-covered with the layer of activating gumboil. The alloys of transitional metals are alloys based on iron, or copper, or nickel, or titanium, or zirconium. After hardening the composite material is extracted from the mould and placed into the water.
EFFECT: extension of nomenclature of the products from layered composite materials, improvement of quality of the composite and decrease of labour input of its fabrication.
