Claims (5)

1. Способ получения пористых полуфабрикатов из порошков алюминиевых сплавов, включающий смешивание порошка алюминиевого сплава с порофором, засыпку полученной смеси в емкость, горячую деформацию полученной заготовки, помещением ее в форму и высокотемпературную термообработку, отличающийся тем, что после засыпки смеси порошков в емкость ведут холодное прессование с последующим нагревом плотной заготовки до температуры на 10-20°С ниже температуры образования самой легкоплавкой эвтетики материала заготовки, горящей деформацией получают проволоку, которую затем перерабатывают на частицы различной формы и размеров, которые перед высокотемпературной термообработкой засыпают в форму.1. A method of obtaining porous semi-finished products from aluminum alloy powders, comprising mixing an aluminum alloy powder with a porophore, filling the resulting mixture into a container, hot deforming the resulting preform, placing it in a mold and high-temperature heat treatment, characterized in that after filling the powder mixture into the container, cold pressing followed by heating the dense workpiece to a temperature of 10-20 ° C below the temperature of formation of the most low-melting eutetics of the workpiece material, burning deformation receive a wire, which is then processed into particles of various shapes and sizes, which are poured into a mold before high-temperature heat treatment. 2. Способ по п. 1, отличающийся тем, что поверхность проволоки перед переработкой на частицы перфорируют. 2. The method according to p. 1, characterized in that the surface of the wire before processing into particles is perforated. 3. Способ по п. 1, отличающийся тем, что засыпку в форму ведут послойно частицами проволоки разного химического состава. 3. The method according to p. 1, characterized in that the filling in the form is carried out in layers by wire particles of different chemical composition. 4. Способ по п. 1, отличающийся тем, что перед высокотемпературной термообработкой частицами засыпают объем формы полностью. 4. The method according to p. 1, characterized in that before the high-temperature heat treatment, the particles fill the mold volume completely. 5. Способ по п. 1, отличающийся тем, что перед высокотемпературной термообработкой, форму засыпают частично. 5. The method according to p. 1, characterized in that before the high-temperature heat treatment, the mold is partially filled.
