METHOD OF PRODUCING COMPOSITE MATERIAL AlO-Al Russian patent published in 2017 - IPC C22C32/00 B22F3/12 B22F3/23 C04B35/117

Abstract RU 2632346 C2

FIELD: chemistry.

SUBSTANCE: method comprises granulating an aluminium powder consisting of plate-shaped particles with stearic coating, pressing the preform from the granular powder and sintering it. Granulation is carried out by heat treatment of the powder in air at the temperature of 375-380°C for 3-5 hours and its subsequent heat treatment in a vacuum at the temperature of 620-650°C for 1-2 hours, the pressing of the preform is carried out at the pressure of 500-1000 MPa, and sintering of the preform is carried out at the temperature of 570-600°C for 1-2 hours.

EFFECT: increasing the relative density and specific effective work of the composite material fracture.
