The last decades are characterized by constantly increasing interest of practically all industrialized countries of the world to the cast discrete reinforced aluminum matrix composite alloys (AMC’s). However, growth of volumes of industrial use of AMC’s for the present isn't adequate to technical and operational opportunities of these new materials. Further development of application of competitive AMC’s today requires conducting large-scale systematic researches and pilot projects in the following groups of problematic questions: the initial charge materials; technological processes of production; technological aspects of complex processing, including recycling; fundamental and applied research and development. Using as matrix alloys for AMC’s of low-grade and sub-standard waste of aluminum alloys requires development of new highly effective methods of their refinement, providing almost total absence of gases and products of a salt component of flux. Analysis of modern scientific and technical information indicates that at present time the most intensively studied and applied in industry liquid phase methods for AMC’s. The most promising methods of manufacturing of isotropic AMC’s are methods of reactionary molding or synthesis (so-called in-situ processes). Currently, industrial synthesis technologies of products from AMC’s still are at the stage of working off or experimental-industrial development. Such condition is partly due to the fact that technologies, as a rule, contain "know-how" and a trade secret. Other important direction of researches on expansion of use of AMC’s in real products of mechanical engineering is development and improvement of technological decisions on multi-purpose processing of AMC’s – thermal, thermocyclic and thermoplastic, mechanical, laser, fusion welding and built up welding, etc., and also search of the most rational ways of machining and recycling of AMC’s. Obviously, the further development of the theory and practice of composite casting is impossible without coordinated scientific researches, efficiency of which is significantly enhanced by the consolidation of scientific and technological potential of scientists and engineers, research institutions, universities and enterprises.
