Abstract

Creation of new functional and structural materials with improved performance characteristics is important in terms of basic and applied research as well as in terms of development of innovative economy. Particular attention is drawn to aluminium matrix composite material (AMCM), thanks to a good combination of performance properties, especially a high specific strength and low cost, which allows their use in various sectors of the economy, which has practical importance for the development of industrial production in the Far East. However, the question of technology for producing such materials based on the study of the mechanisms of the structure formation is still not fully understood. The reason for this is that the choice of mode of production AMCM due primarily to the need for: strengthening the material, producing a given distribution of the reinforcing component to ensure good adhesion between matrix and filler, ensure that no chemical interaction at the interface. Recently, widely used liquid phase AMCM production technology, since they are often more cost-effective, technologically easier and provide high mechanical properties of the material due to the strong coupling at the interface matrix-filler. But reinforcing the interaction with the matrix components, the formation of structure and properties is poorly understood, which complicates the industrial application of such technologies. Among AMCM composites with the main alloying element boron had received relatively widespread use, because they posses a unique combination of properties such as low specific density, strength, corrosion resistance, good thermal conductivity, and the ability to absorb thermal neutrons, which are important for nuclear energy in terms of the manufacture of radiation undertray structures. Therefore, the creation of new boron AMCM with high physical-mechanical characteristics of the liquid phase and the development of production technologies is an urgent task.

The work was based on an agreement and creative collaboration between the engineering centers of National University of Science and Technology “MISiS” and the Research and Education Center “NANO” (Far Eastern Federal University).
