FIELD : metallurgy. SUBSTANCE : casting magnesium alloy with rare earth metals is proposed. The alloy contains, wt % : Y of more than 5.0 to 7.0; Gd 5.0 to less than 7.0; Sm 1.0-5.0 when the ratio (Y+Gd) : Sm of from 2.8 to less than 14.0; Zr 0.2-0.6; Mg is the rest. EFFECT : alloy is characterized by high strength and heat resistance indicators achieved at the optimum combination of alloying components and reduced time of hardening heat treatment. 3 dwg, 2 tbl, 7 ex
