The picture shows regression analysis of the mass gain curves and the rate of mass gain depending on oxidation time obtained for samples of the TNM, TNZ and TNZ+ alloys in the near duplex (1 and 2) and near lamellar (3 and 4) conditions subjected to oxidation at 800°C.

Change in sp2-hybridization to sp3 results in an increase of Young's modulus and a decrease of Poisson's ratio for bornitrane. The substitution of carbon atoms by B and N atoms in the lattice of graphyne and graphene, leads to a decrease in Young's modulus.

SEM - images of characteristic elements of the SCMnCr 3 steel surface after spark assisted deposition of the tin bronze coating (a, c - spherical particles; b - sponge-like structure; d - influxes; e - cracks; f - the result of the collision of a liquid drop with the surface; g - pore )

Microadditions of yttrium has resulted in a decrease in the average grain size of low-activation austenitic steel. The decrease in the efficiency of dispersion strengthening by carbide particles has led to a slight decrease in the strength properties of the new steel. MC particles are containing Ti, V, Ta and W surrounding Y kernel.

Simulation of a uniaxial tension-compression test of a composite with Maxwellian constituents gives average stresses in the matrix, inclusions and the whole composite.

Using the molecular dynamics method, a study was conducted on the influence of structural defects, carbon and hydrogen impurities, as well as the presence of a shell of another metal, on the melting temperature of metallic nanoparticles.

Based on the results of tests for three-point bending, the dependences σ-ε were constructed for samples CrMnFeCoNiZr alloy in the initial state (as-cast) and after HPT. The samples in their initial state exhibit typical plastic behavior even with deformations of more than 10%. HPT processing of samples leads to brittle-plastic behavior of the material.

The microstructure of alloys containing 2.4, 3.2 and 4 wt. % Sb sintered at 1300 °C. After Hopkinson's test, adiabatic shear bands were formed in alloys containing 3.2 and 2.4 wt. % Sb.

Dispersion strengthening of the γ-phase particles by the γ′-phase particles in shape memory NiFeGa(B) alloys occurs during hot rolling and subsequent annealing. The optimal texture of the annealed crystals with the special microstructure, should contribute to strengthening the material without cracking along the grain boundaries.

The microstructure of heat-resistant dispersion-hardened 12% chromium ferritic-martensitic steel 16Cr12MnWSiVNbB (type EP-823) demonstrates good thermal stability during aging at 450°C for 5000 h. This maintains its strength properties at the initial level.

The informative drawing shows the structure of CrMnCN steel and the features of its deformation behavior at subzero temperatures.

Strain energy of the diamane molecule and its BN analogue.

To assess slippage at HPT, the “joint torsion of the disk halves” method was used.

This paper presents a method for determining elastic constants — the elastic modulus and Poisson's ratio of 3D-printed materials using uniaxial tension test on rectangular cross-section samples. It is proposed to conduct longitudinal and transversal strain measurements on the surface of the samples using fiber-optic sensors based on fiber Bragg gratings, which offer comparable accuracy to standard electrical strain gages while providing advantages such as reduced size, simplified preparation, and minimal equipment requirements

This review is focused on the recent progress on the relationship between nitrogen-assisted hardening mechanisms and mechanical properties of the CoCrFeMnNi-N family alloys. The basic physical problems, including fabrication of the nitrogen-alloys Cantor alloy, solubility of N in CoCrFeMnNi system, as well as the influence of nitrogen alloying on strength properties of the CoCrFeMnNi-N alloys have been discussed.
