The present work aims to provide the differences in elasticity of pentagonal wires and rods within the framework of distributed and single disclination models, employing both the analytical technique and the finite element method.

Schematic diagram of the ECAP installation with simultaneous application of ultrasound: 1 – ultrasonic generator; 2 – converter; 3 – waveguide, 4 – matrix, 5 – punch, 6 – sample.

The surface state of the plates to be welded has a significant effect on the strength and fracture energy of copper joints produced by ultrasonic welding.

A novel metal-matrix composite, in which a soft Al-matrix is strengthened by hard and inert Pt-particles was obtained. Severe plastic deformation and large shear strain implemented under HPT lead to the formation of solid solutions and the amorphization on the interfaces.

The contributions of dispersion and solid solution hardening mechanisms are comparable and provide a smaller contribution to the YS improvement of the Ti6Al4V-Cu alloys as compared to that the grain-boundary hardening

The influence of COOH and C=O groups on the I-V characteristics of graphene nanomesh. Depending on the type of group, one can either strengthen or weaken the effect of negative differential resistance on the I-V characteristic.

After the LEHCEB treatment, the corrosion resistance of the coatings increased significantly, as evidenced by the decrease in corrosion current and the increase in polarization resistance. In addition, the bond strength of the coatings also increased, as evidenced by the increase in critical load from 9.9 to 19.2 N.

Multiaxial isothermal forging significantly improves stress corrosion cracking resistance of the ZX10 alloy

The stability concentration region of magnesium-containing pyrochlores based on bismuth tantalate (Bi2+xMg1+yTa2-yO9-δ, -0.11≤x≤0.325, -0.01≤y≤0.20) was experimentally determined. The microstructure of samples was studied depending on the molar ratio Bi/Ta,Mg and Mg/Ta.

Tensile strain behavior accompanied by low and high duty cycle current

ZnO Powder Doped with Fe after Solution Combustion Synthesis and Calcination.

The influence of a silver shell on the processes of melting and crystallization of copper nanoparticles was studied using the molecular dynamics method

Model of elastic ferromagnetic film with free boundaries. Interaction parameters depend on variable distances between sites.

The microcrystalline strain ε(P) in highly compressed La3Ni2O7-d superconductor was determined in the pressure range of 1.6 GPa ≤ P ≤ 41.2 GPa. We found that ε(P) has a three-dome shape in this pressure range.

Variations of measured disorientations distinctly increase at too high scanning steps owing to the contribution of interfacial GND. Accordingly, to derive SSD density from a slope of disorientation dependence on the scanning step, the latter is properly limited.
