The basic regularities of the physical nature of strength of directionally solidified eutectic alloys (LaB6-MeB2, B4C-MeB2, Ti-TiB, Mo-Si-B, etc.) have been defined by systematic studies of the influence of the nature of the matrix and reinforcing phases, their structural-geometric characteristics, and stress-strain state on the temperature dependence of mechanical characteristics of composite materials.

Created physical fundamentals of process control production of wear-resistant high temperature metal and ceramic material reinforced single crystalline fibers of superhard refractory compounds during high-speed sintering directional solidification of melt eutectic alloys quasi binary systems (LaB6-MeB2, B4C-MeB2, WC-W2C, Ti-TiB2) and subsequent heat treatment.

The influence of the kinetic parameters of the process of directional solidification from the melt and directional sintering in the dispersed state, crystal chemistry and diffusion properties of the initial components, energy parameters of elastic waves, the nature of alloying components on the structural and geometric characteristics of the phase components of ceramic composite materials are investigated.
