Description

Предложенный спеченный алюминиевый сплав САС-1 предназначаетс  дл  получени  прессованных полуфабрикатов, детали из которых изготовл ютс  методом механической обработки, и отличаетс  от известных содержанием 25-30% кремни  и 5-7Vo никел , что обеспечивает низкий коэффициент линейного расширени , герметичность сплава и его свариваемость.The proposed CAC-1 sintered aluminum alloy is intended for producing pressed semi-finished products, parts of which are made by mechanical processing, and differs from the known content of 25-30% silicon and 5-7Vo nickel, which ensures a low linear expansion coefficient, hermeticity of the alloy and its weldability. .

Сплав приготовл ют из меоткодисперсных хорошо перемешиваемых порошков с размером частиц не более 100 микрон на распылительной установке. Дл  получени  прутков из сплава порошок прессуют в нагретом состо нии в брикеты, которые затем обтачивают и нагревают, выдержива  при 500-530° 2 часа, носле чего из брикетов получают прутки . Предложенный снлав имеет следующие механические и физические свойства.The alloy is prepared from well-dispersed well-mixed powders with a particle size of not more than 100 microns in a spray unit. To obtain alloy bars, the powder is pressed into briquettes in a heated state, which are then turned and heated, holding at 500-530 ° for 2 hours, and then bars are obtained from the briquettes. The proposed snlav has the following mechanical and physical properties.

Модуль упругости при раст жении 8000 кг1мм, цредел прочности 24 кг/мм, предел текучести 23,0 кг/лat, относительное удлинение 0,5%, твердость по Бринеллю 130 ед., удельный вес (нри 20°) 2,75 г1см, коэффициент линейного расширени  снлава в интервале температур от 20 до 100° составл ет (14,5-15,5) .10 град .The modulus of elasticity when stretching 8000 kg1mm, tensile strength 24 kg / mm, yield strength 23.0 kg / lat, relative elongation 0.5%, Brinell hardness 130 units, specific weight (at 20 °) 2.75 g1cm the coefficient of linear expansion of the fusion in the temperature range from 20 to 100 ° is (14.5-15.5) .10 degrees.

Предложенный сплав может быть с успехом применен в вакуумном приборостроении.The proposed alloy can be successfully applied in vacuum instrumentation.
