Summary:

The trends of development of industrial production of the casting aluminum matrix composites (AMC) reinforced by highmodulus non-metallic fillers were discussed. The analysis of the dynamics of total world production and consumption of aluminum-based alloys including AMC was performed. It is shown that the total consumption of metal matrix composites, in spite of the annual growth rate of 5,7-5,9%, now accounts for only about 0.01% of the total global production of aluminum. It is concluded that the elimination of the existing restrictions of production processes of casting AMC consists primarily in ensuring the availability of reinforced fillers, as well as manufacturability and ease of implementation of the metallurgical processes of synthesis of casting particulate reinforced AMC.

Keywords:

Metal matrix composites, aluminum-based alloys, synthesis of composite alloys, non-metallic fillers.
