Ductile-brittle transition behavior of medium-carbon steel with 0.32 %C-1,35 %Mn-0,003 %B by instrumented impact testing and fracture analysis was studied. On the load-displacement curves the periods corresponding to different zones of crack propagation are distinguished. Each period can be quantitatively described by a set of strength, plastic and gradient parameters.

It was found that the electric pulse treatment of cryorolled cooper leads to the development of recovery processes and continuous static recrystallization, provides a transition from in-situ recrystallization to grain growth, which leads to a sharp decrease in hardness.

In the microstructure of ZrO2 based composites, both undivided, entangled bundles/aggregates of SWCNTs and individual nanotubes are observed, which together form a continuous reinforcing structure, which leads to a refinement of the grain size of the composites.

The phase transformation of the t → m type determines the inelastic stage of deformation of ceramics based on zirconium dioxide stabilized by additives of yttrium oxide. The maximum deflection force of the cantilevers of a two-cantilever specimen with a chevron notch, tested by wedging, determines the critical characteristics of the crack resistance of ceramics ZrO2 + 3mol% Y2O3: the rate of energy release Gc during crack propagation (specific energy of destruction) and the stress intensity factor KIc. The maximum viscosity is characteristic of ceramics with the composition ZrO2 + 3mol%Y2O3, the deviation from which reduces the fracture toughness. The increase in fracture toughness is favored by the grinding of the powder in a planetary mill.

Under shock-wave loading at a speed of 471 m / s at 20 °C, a phase hammer hardening of austenite is observed as a result of cyclic γ → ε → γ transformation, which manifests in the form of an increased dislocation density (2 × 1010 cm-2) at the site of former ε-martensite crystals.

We studied the structure, phase composition, and mechanical properties of the FeCrMnNiCo0.85C0.15 alloy in the cast and annealed (at 1200°C, 1 h) states, as well as after multistage thermomechanical treatments, including high-temperature annealing, hot forging, and cold rolling. Thermomechanical treatments do not provide the formation of a single-phase austenitic structure, but contribute to a significant dissolution of carbides and an increase in the solid solution hardening of the austenite phase. Such alloys have significantly higher strength and ductility values in comparison with cast alloy and Cantor alloy.

From the interpretation of the obtained XPS- and NEXAFS 2p-spectra of atoms in Co-doped CaCu3Ti4O12 and the corresponding oxides it was concluded that in ceramics the copper and calcium atoms have a charge state of +2, the titanium atoms have a slightly lower charge than +4, and cobalt atoms have mainly a charge of +2 with some fraction of Co(III) ions in the high spin state.
