METHODS OF PRODUCING OILFIELD DEGRADABLE ALLOYS AND CORRESPONDING PRODUCTS Russian patent published in 2013 - IPC C22C1/00 C22C1/04 

FIELD: chemistry.

SUBSTANCE: method of producing a degradable aluminium alloys involves adding to molten aluminium or aluminium alloy, one or more alloying elements selected from a group comprising gallium (Ga), mercury (Hg), indium (In), bismuth (Bi), tin (Sn), antimony (Sb), thallium (Tl), magnesium (Mg) and zinc (Zn), wherein the one or more alloying elements are added in form of solid pre-moulded additives and dissolving the alloying elements in the molten aluminium or aluminium alloy to form a degradable aluminium alloy. If the one or more alloying elements are liquid at ambient temperature, said one or more alloying elements are combined with a nonmetallic or metallic carrier. The nonmetallic carrier is made of plastic, ceramic or refractory materials, and the metallic carrier is selected from a group consisting of lithium, magnesium, nickel and zinc.

EFFECT: obtaining a degradable aluminium alloy and components made therefrom, having a balanced combination of properties, specifically rate of decomposition, strength, impact viscosity and density.
