METHOD OF RECEIVING OF CAST HIGH-REINFORCED ALUMO-MATRIX COMPOSITE MATERIAL Russian patent published in 2009 - IPC C22C1/10 B22F3/15 C22C21/00

Abstract RU 2356968 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy field, particularly to method of receiving of cast high-reinforced alumo-matrix composite material. Method includes particles heating of silicon carbide in bulked condition up to the temperature 850-900°C and particles infiltration by aluminium alloy, heated up to the temperature 850-900°C during the mechanical agitation. The received composite mixture is subject to hot double-ended compressing in heated up to the temperature of composite mixture preparation mould at pressure 2.0-2.2 GPa. Additionally inclusion volume fraction of silicon carbide particles in total value of the material is from 30 up to 80%.

EFFECT: uniform distribution of components in volume of composite material.
