STRUCTURE AND PROPERTIES OF REINFORCED CERAMIC MATERIALS PRODUCED BY DIRECTIONAL CRYSTALLIZATION

Abstract

The paper describes advances in one of the promising areas for the development of Samsonov's scientific school at the Igor Sikorsky Kyiv Polytechnic Institute. The main results are presented to refine the mechanisms whereby crystals nucleate and grow from melts of eutectic alloys and acquire their microstructure and phase composition and the mechanisms whereby reinforced composite materials with an isotropic and anisotropic microstructure are strengthened for operation in extreme conditions involving high-speed heating and cooling, impact interaction, cyclic loading, and corrosive environments. The mechanical properties of reinforced composite materials in a wide temperature range are presented. Areas for application of the reinforced ceramics are identified.
