FEATURES OF MANUFACTURE OF COMPOSITE MATERIAL WITH MACROHETEROGENEOUS STRUCTURE WITH THE APPLICATION OF MAGNETIC FIELDSA. S. KALINICHENKO, V. A. SHEINERT, V. A. KALINICHENKO, A. G. SLUTSKY, Belarusian National Technical University, Minsk, Belarus, 65, Casted composite materials have found application in various branches of industrial production. However, there are still a number of problems related to the choice of optimal technology for their synthesis and the solution of which will help to achieve in practice high level of properties predicted by the theory and provide the control of interfacial interactions to enhance the stability of the structure and properties of composites. There is s need in additional research related to the development of new types of reinforcing elements, which will provide the raise in the level of performance of the composite. It is established that an important role plays not only the type of the matrix but also the chemical composition and microstructure of the reinforcing material. This would require research on optimization of technology for production of composite materials during the solid-liquid synthesis. The paper presents generalized results of experimental studies of peculiarities during the formation of composite materials on the basis of bronze and iron granules with the use of high-speed induction melting. As reinforcing phase iron granules DCHL with a diameter of about 1 mm were used.Keywords. Inductive heater, control unit, high speed melting, composite materials, macro-and microstructure. Литые композиционные материалы нашли применение в различных отраслях промышленного про-изводства [1][2][3]. Однако имеется еще ряд проблем, связанных с выбором оптимальной технологии их синтеза, решение которых обеспечит достижение на практике предсказываемых теорией свойств компо-зитов, управление межфазным взаимодействием для повышения стабильности структуры и свойств композитов. Необходимы и дополнительные исследования, связанные с разработкой новых видов арми-рующих элементов, которые позволят поднять уровень эксплуатационных характеристик композита. На-пример, композиционные материалы на основе меди разрабатываются, главным образом, для триботех-нического применения, так как они обладают повышенными антифрикционными свойствами [4].
