Description
(54) ЛИТЕЙНЫЙ СПЛАВ НА ОСНОВЕ АЛЮМИНИЯ(54) FOUNDRY ALLOY BASED ON ALUMINUM
1one
Изобретение относитс к области изыскани литейных сплавов на основе алюмини , предназначенных дл получени фасонных тонкостенных отливок при литье в песчаноглинистую и металлическую формы, по выплавл емым модел м, а также при литье под низким и высоким давлени ми.The invention relates to the field of finding cast alloys based on aluminum, designed to produce shaped thin-walled castings when casting in sandy clay and metal forms, in melted models, as well as in casting under low and high pressures.
Известен литейный сплав на основе алюмини , содержащий (в вес.%):Known foundry alloy based on aluminum, containing (in wt.%):

Предлагаемый сплав отличаетс от известного наличием германи . Это способствует повышению жидкотекучести, трещиноустойчивости , механических свойств сплава и снижению линейной усадки.The proposed alloy differs from that known for the presence of germanium. This contributes to an increase in fluidity, crack resistance, mechanical properties of the alloy and a reduction in linear shrinkage.
Сплав имеет следующий химический состав (в вес.%):The alloy has the following chemical composition (in wt.%):

Остальное.Rest.
Литейные свойства сплава следующие: Жидкотекучесть по U-образной пробе при температуре формы 50-55°С и температуре заливки 710°С, мм 340-370 Жидкотекучесть по стандартной спиральной пробе при температуре заливки 700°С, мм 980 Линейна усадка, %1,05-0,99The casting properties of the alloy are as follows: Fluid flow through a U-shaped sample at a mold temperature of 50-55 ° C and a pouring temperature of 710 ° C, mm 340-370 Liquid fluidity from a standard spiral sample at a pouring temperature of 700 ° C, mm 980 Shrinkage linear,% 1, 05-0.99
Трещиноустойчивость по гребешковой Т-образной пробе при литье под давлением , гребешки5Cracking resistance on comb-shaped T-shaped test during injection molding, scallops5
Механические свойства сплава приведены в аблице.The mechanical properties of the alloy are given in the table.
Предмет изобретени Subject invention
Литейный сплав на основе алюмини , включающий кремний, медь, магний, титан, бор, отличающийс тем, что, с целью повышени жидкотекучести, трещиноустойчивости, механических свойств и снижени линейной усадки, он дополнительно содержит германийAluminum-based foundry alloy, including silicon, copper, magnesium, titanium, boron, characterized in that, in order to improve fluidity, crack resistance, mechanical properties and reduce linear shrinkage, it additionally contains germanium
