ALUMINUM-BASED ALLOY FOR MANUFACTURING STRUCTURAL FOIL, METHOD OF PREPARING INGOTS FROM ALUMINUM-BASED ALLOY FOR MANUFACTURING STRUCTURAL FOIL, AND A METHOD FOR MANUFACTURING STRUCTURAL FOIL FROM ALUMINUM-BASED ALLOY
ALUMINUM-BASED ALLOY FOR MANUFACTURING STRUCTURAL FOIL, METHOD OF PREPARING INGOTS FROM ALUMINUM-BASED ALLOY FOR MANUFACTURING STRUCTURAL FOIL, AND A METHOD FOR MANUFACTURING STRUCTURAL FOIL FROM ALUMINUM-BASED ALLOY
FIELD: nonferrous metallurgy.;SUBSTANCE: invention is intended for use in metallurgy, mechanical engineering, and aircraft industry, in particular for manufacturing honeycomb structures. Alloy is composed of, wt %: magnesium 8-10, manganese 0.1-0.15, zirconium 0.15-0.2, cobalt 0.05-0.2, boron 0.005-0.007, beryllium 0.001-0.02, iron 0.15-0.2, silicon 0.15-0.2, titanium 0.1-0.2, aluminum - the balance. Ingot for manufacturing structural foil is obtained by semicontinuous casting in rotary crystallizer at volumetric cooling 4-20C/sec. Structural foil manufacturing process comprises homogenization, hot rolling, annealing, cold rolling followed by annealing in air atmosphere, second cold rolling followed by annealing, and final cold rolling.;EFFECT: increased strength of alloy at ambient and elevated temperatures and improved processability un rolling stage.;3 cl, 3 tbl
