The process of plastic deformation of multicomponent ceramics based on the MAX phase at room temperature and at higher (1000 °C) temperature has been studied by dilatometry and microindentation. Based on the experimentally obtained dependence of the

The paper discusses the conditionality of such physical properties of polycomponent oxygen-free ceramics (MAX phases), as thermal and fracture resistance, with a special physicochemical nature of the binding forces between the elements forming the MA

For CeO₂ nanocrystals a large number of cerium ions undergo Ce⁴⁺→ Ce³⁺ transition leading to formation of oxygen-deficient CeO₂₋x phase in the subsurface layer of nanocrystal. Such structural rearrangement leads to density gradient in

Evolution of dislocation structure during formation of the contact area was studied in modeling experiments "wedge-plane" for KCl single crystal under loading at room and high (0.8Tm) temperatures. It was shown that at the first (rapid) stage of the

The regularities of disc-like voids (cracks) healing in polycrystalline copper samples under conditions of uniaxial compression at 600°C were experimentally studied. The theory of crack healing by diffusion-dislocation mechanism was developed. Compa

Using light-scattering method, the cracks formation was experimentally studied in NaCI single crystals under uniaxial cyclic compression (10⁷ N/m²) during ~10 c at room temperature and following annealing at T = 500°C for ~10 min. The observed cr
