ALUMINUM-BASED CASTABLE ALLOY Russian patent published in 1999 - IPC

FIELD: nonferrous metallurgy. SUBSTANCE: alloy is composed of, wt %: magnesium 6.5-7.5, silicon 0.1-0.6, manganese 0.2-0.6, titanium 0.05-0.3, iron 0.05-0.2, beryllium 0.01-0.1; one of following compounds from the group: scandium 0.01- 0.2, bismuth 0.01-0.4, silicon carbide 1.0-5.0, silicon nitride 0.1-7.0, aluminum oxide 1.0-5.0, zirconium oxide 1.0-5.0; and aluminum - the balance. Alloy can find use in manufacture of parts operated under friction and elevated impact loads. EFFECT: increased plasticity and impact resistance due to additional alloying of solid solution, disintegration of all structural constituents and receiving disperse hardener in the form of nonmetal particles. 2 tbl
