Abstract
Section titled āAbstractāSummary . P roblem statement Among the developed technologies metal-composites production,a special place takes powder metallurgy, having fundamental differences from conventionally used foundry technologies. The main advantages of this technology are: the possibility of sensetive control, the structure and phase composition of the starting components, and ultimately the possibility of obtaining of bulk material in nanostructured state with a minimum of processing steps. The potential reinforcers metals include micro and nano-sized oxides, carbides, nitrides, whiskers. The special position is occupied with carbon nanostructures (CNS): Š” 60 fullerenes, single-layer and multi-layer nanotubes, onions (spherical bulbs), nano-diamonds and graphite,their properties are being intensively studied in recent years. These objects have a high thermal and electrical conductivity values, superelasticity, and have a strength approximate to the theoretical value, which can provide an obtaining composite nanomaterial with a unique set of physical and mechanical properties. In creation of a metal matrix composite nanomaterials (CM), reinforced by various CNS, a special attention should be given to mechanical activation processes (MA) already at the stage of preparation of the starting components affecting the structure, phase composition and properties of aluminum-matrix composites.
