On the base of the results determined by using modern physical material science methods scientific principles referred to relationships of structure, phase composition, physical and mechanical properties formation of frame metal-ceramic composites based on tungsten carbide with a multicomponent high-entropy alloy (HEA) binder during high-speed electron-beam and induction sintering has been developed for the first time and will play an important role in deepening the understanding of the processes of structure formation in dispersed heterogeneous systems.

For the first time physical representations and theoretical assumptions about the regularities of the influence of quasi-hydrostatic compression, as the most stringent conditions of deformation, on the composition, phase transformations, structure, strength and plastic properties of crystalline metal-like and quasicrystalline metal phases, including titanium hydride with a high hydrogen content and Al-Fe-Cr alloy with finely dispersed particles of quasicrystalline phases.

On the base of the results determined by using modern physical material science methods scientific principles referred to relationships for combined effect of sever plastic deformation and temperature on diffusive processes, phase transformation, evolution of structure and thermal stability of mechanical properties of nanostructured composite Al alloys reinforced by ultra fine particles of metastable quasicrystalline phases has been developed for the first time.
