METHOD OF PRODUCTION OF MAGNESIUM ALLOY Russian patent published in 2002 - IPC

FIELD: metallurgy; aeronautical engineering; production of high-purity corrosion-resistant magnesium-based alloys. SUBSTANCE: proposed method includes melting of charge, alloying, mixing magnesium melt to homogeneous state, refining the melt from iron; refining the melt is conducted by means of zirconium from magnesium-zirconium alloy at zirconium-to-iron ratio in melt of 0.1 to 2.0; magnesium-zirconium alloy is introduced in melt in the amount of 0.1 to 0.2% of mass of charge at temperature of 710 to 735 C; magnesium- zirconium alloy is introduced in melt together with titanium sponge at titanium-to-iron ratio of 0.5 to 2.5; alloying of melt is performed by means of aluminum and one or several metals selected from group including zinc, manganese, calcium, cadmium, beryllium and rare-earth metals. Alloy thus obtained has fine-grained structure, enhanced corrosion and mechanical resistance. EFFECT: reduced labor consumption; reduced power requirements; increased utilization factor. 4 cl, 1 tbl
