Analysis of technological parameters of cast composite materials with a matrix of light alloys manufacture.The successful functioning and further development of most modern industries, such as aerospace, transport, military, biomedicine, is not possible without the use of lightweight, durable and inexpensive materials to manufacture. Light alloys are widely used in industry and everyday life due to the high complex of physical and mechanical properties, wear and corrosion resistance as well as low cost. In this regard, the use of light alloys as a basis for composite materials is justified and expedient. The properties of the finished composite material exceed the properties of its constituent components. The potential of these materials has not been fully used to this day despite the growing interest in metal matrix composites and extensive investigations aimed at the development of production technology and the introduction of advanced systems based on light matrices. The article presents a brief review of the literature on the analysis of the main components of the technology of cast composite materials (CCM) based on light alloys of aluminum and magnesium reinforced by particles of different types. Particular attention is paid to the choice of the matrix alloy, the type, size and amount of reinforcing particles introduced into it, as well as the thermal-time and kinetic parameters of the process. The matrix alloy must be uniform, strong, light and inexpensive. The particles must have a high hardness and be optimally distributed in the matrix, to be securely fixed in it. An important element of the technology of manufacturing CCM by liquid-phase method is also a method of introducing solid particles of liquid metal. Several ways of introducing reinforcing particles into the melt were analysed too. Only the optimal combination of all these elements can provide composite materials with a high level of physical, mechanical and operational properties. In addition, the article suggests directions for further research in this area.
