Stress-induced martensite aging accompanied ω-phase precipitation in NiFeGaCo single crystals
The effect of ω-phase particles precipitated prior to or during stress-induced martensite aging (SIM-aging) on the two-way shape memory effect (TWSME), reversible strain, thermal hysteresis and martensite formation temperature has been established in Ni47.5Fe15Ga27.5Co10 single crystals. The experiment was conducted on single-phase quenched single crystals. In contrast, SIM-aging was accompanied by the precipitation of ω-phase particles in oriented L10-martensite, and on heterophase single crystals, where ω-phase was previously precipitated in unloaded L21-austenite, whereas SIM-aging was not accompanied by particle precipitation. The TWSME characterized by optimal parameters: a high reversible strain of up to 4 %, narrow thermal hysteresis (15–30 K), and high temperatures ( up to 417 K) obtained in heterophase Ni47.5Fe15Ga27.5Co10 single crystals, in which ω-phase particles precipitated before SIM-aging in the austenitic L21-phase, compared with quenched single crystals, where nanoscale ω-phase particles precipitated in the oriented L10-martensite during SIM-aging.

The use of selective laser melting for the manufacture of metal cells with the geometry of a triply periodic minimal surface ‘gyroid’ are discussed. The samples were made of 12Kh18N10T stainless steel. To study the effect of wall thickness on the physical and mechanical properties of materials with a triply periodic minimal surface geometry, a series of samples with dimensions of 30 × 30 × 30 mm3, with wall thicknesses ranging from 0.1 to 0.8 mm and an elementary cell size of 10 × 10 × 10 mm3. During the study, the specific energy absorption of the developed volumetric product obtained using additive technologies was evaluated. It was shown that the products have high strength and energy absorption characteristics necessary for use in many industries, and can also be used in protective structures.

Energy-absorbing metamaterials based on DNA helices
The increasing demand for vehicle safety creates a need to develop of efficient protective systems with enhanced energy absorption performance. The results of the development and investigation of energy-absorbing metamaterials based on the DNA chain structure are presented. Computer simulation was carried out for preliminary determination of the metamaterial properties. Samples manufactured from Ti6Al4V alloy by the selective laser melting method were tested under quasi-static and dynamic compression. It was established that the specific energy absorption of the metamaterials under dynamic testing was 32.34 J/g, and under quasi-static testing, 14.22 J/g. The metamaterial withstands deformations exceeding 50 % without failure. The obtained results confirm the promising potential of the developed geometry for producing mechanical metamaterials with enhanced energy-absorbing characteristics.

Effect of silicon microalloying on microstructure and HVOF spraying behavior of AlCrFeCoNi high-entropy alloy coating
This study investigates the effect of 0.11 wt. % Si microalloying on AlCrFeCoNi high-entropy alloy coatings produced via mechanical alloying and HVOF spraying. Optimal milling times were 7.5 h for the base alloy and 10 h for the Si-modified one. Spark plasma sintering revealed mixed Body-Centered Cubic and Face-Centered Cubic structures with silicide precipitates. Preliminary abrasive wear tests indicated a tendency for surface stabilization in the Si-modified alloy due to tribo-oxide films. Crucially, during HVOF, Si preferentially oxidized, shielding Cr from burnout (17.64 vs. 14.16 % in the base coating) and significantly improving coating adhesion by eliminating through-cracking, forming a monolithic structure.

Formation of subboundaries in cellular structures during plastic deformation of mono- and polycrystals
The mechanisms of the formation and evolution of dislocation cellular structures in single crystals and polycrystals are investigated using correlation instability in a dislocation ensemble. It is shown that at the nonlinear stage of the system evolution, a cellular structure develops, characterized by both total and excess dislocation densities. At a certain stage in the dislocation ensemble evolution, equilibrium configurations form: configurations with excess density represent sub-boundaries, and those with total density represent dislocation dipole configurations that annihilate via the dislocation climb mechanism. It is shown that the occurrence of sub-boundaries is associated with rotational instability caused by the formation of walls in the regions of maximum values of excessive dislocation density in a cellular dissipative structure. Upon unloading, the dissipative structure is destroyed, and the remaining dislocations migrate into sub-boundaries, leaving behind an equilibrium "framework" of the subgrain structure.

Determining the effective radius of a triple junction of grain boundaries using molecular dynamics
Two methods are proposed for determining the effective radius of triple junctions of grain boundaries based on the analysis of the self-diffusion coefficient distribution in the junction region and the potential energy distribution of atoms. Both methods are considered using the example of triple junctions of high-angle tilt boundaries with and misorientation axes in nickel with varying contents of excess free volume. Triple junctions in the model were created by simulating the crystallization of a melt from three differently oriented crystalline seeds. Excess free volume was introduced into the triple junction by removing the corresponding number of atoms from the initial computational cell. During crystallization, the introduced free volume concentrated predominantly in the grain boundaries and triple junction regions, with the free volume fraction increasing toward the junction site. With increasing excess free volume in the triple junctions, self-diffusion proceeded more intensively. The diffusion intensity within the triple junction itself was generally distributed non-uniformly and increased toward the junction center. It is shown that the effective radius of the triple junction, determined using both methods based on the diffusion coefficient and atomic energy distributions, increases with the free volume content.

Thermoelastic Rayleigh waves in an isotropic half-space
The process of the Rayleigh wave propagation in an elastic isotropic half-space with consideration of the interaction between the temperature and the mechanical fields is studied. The mathematical setting of the problem includes a related system of equations of thermoelasticity in displacements. The solution is sought in the form of a progressing thermoelastic wave. A dispersion equation is obtained that relates the frequency of the propagating wave to the components of the wave vector, the solution of which is found analytically. Taking into account the trivial boundary conditions expressing the absence of mechanical loads and heat fluxes at the boundary of the half-space, an equation is formulated to determine the frequency of a thermoelastic Rayleigh wave. Analytical expressions for displacement amplitudes and temperature are obtained. A series of numerical calculations was performed for various materials. The calculation results are presented in the form of tables and graphs. The effect of the mechanical characteristics of materials on the amplitudes and frequencies of elastic and thermoelastic Rayleigh waves is studied. It is demonstrated that the interaction of mechanical and temperature fields in real materials is very weak, and the amplitudes and frequencies of Rayleigh waves coincide in the elastic and thermoelastic cases. Thermoelastic effects depend essentially on the linear thermal expansion coefficient, and the parameters of elastic and thermoelastic Rayleigh waves start to differ significantly as the latter increases.

Statistical approaches for studying the strength properties of ZSM-5-based extrudates with different zeolite framework Si/Al ratios
The influence of ZSM-5 composition on the mechanical strength of extruded alumina–ZSM-5 catalysts is studied. For samples with zeolite content ranging from 0 to 95 % and Si/Al ratios of 11.5, 15, and 25, the compressive strength was measured and described by a normal distribution and Weibull statistics. Strength depends non-linearly on zeolite content, peaking at 20 wt. % for all series. ZSM-5 with Si/Al = 15 yields statistically higher strength than Si/Al = 11.5 or 25. The Weibull modulus increases with zeolite content, indicating a more homogeneous granule structure. The observed differences are attributed to the particle size distributions: maximal strength occurs when the bimodal ZSM-5 distribution efficiently complements the pseudoboehmite particles, ensuring optimal packing and binding.

Effect of technology of thermoelectric BiSbTe alloys on structural, thermoelectric and mechanical properties
The parameters of the main technologies for producing thermoelectric materials are considered: zone melting and extrusion. The structure and properties of samples of thermoelectric BiSbTe alloys obtained by zone melting and hot extrusion are compared to identify the dependencies. The analysis was carried out using methods of X-ray phase analysis, metallographic analysis, Raman spectroscopy, investigation of thermoelectric properties by the probe method, and mathematical modeling. The dependences of the thermal EMF distribution over the cross section are obtained, and the experimental dependences are analyzed. As a result, it was revealed that the samples obtained by hot extrusion have a heterogeneity of structure and properties across the sample section, which is associated with a stress-strain state due to the presence of significant friction forces on the surface of the contact of the material with the matrix. No such patterns were found for samples obtained by zone melting.

First-principles calculations to investigate structural, electronic, and optical properties of Na doped TaO₃ perovskite
A comprehensive first-principles study on the structural, electronic and optical properties of perovskite NaTaO₃ using the full-potential linearised augmented plane wave plus local orbitals (FP-LAPW + lo) method, as implemented in the WIEN2k code was carried out. Five structural polymorphs (orthorhombic (Pbnm and Cmcm), tetragonal (P4/mbm and P4/mmm), and cubic (Pm-3m)) using both the generalized gradient approximation (GGA) and the Tran–Blaha modified Becke–Johnson (TB-mBJ) exchange-correlation potentials were systematically optimized. Total energy calculations show that the ground state is the orthorhombic Pbnm phase, with the Cmcm, P4/mbm, P4/mmm and Pm-3m phases at + 0.021, + 0.038, + 0.052 and + 0.074 eV per formula unit in energy, respectively. The calculated lattice parameters and bulk moduli agree well with the experimental data. The bulk modulus decreases from 197.37 GPa (Pbnm) to 192.42 GPa (Pm-3m) indicating a decreased structural rigidity with increasing symmetry. The electronic structure analysis shows that the Pbnm phase is a direct-band-gap semiconductor with a bandgap of 2.75 eV (GGA) and 3.15 eV (TB-mBJ) at the Gamma point, respectively, which is in better agreement with the experimental value of 3.98 eV. The valence band is mainly composed of hybridized O-2p and Ta-5d orbitals whereas the conduction band minimum is mainly of Ta-5d character.
A detailed analysis of optical properties, i.e., complex dielectric function, refractive index, absorption coefficient, reflectance and energy loss function, shows strong absorption in the UV region with a threshold 3.15 eV (TB-mBJ), low reflectance in the visible region and sharp plasma edge at 7.65 eV (TB-mBJ). The results presented here indicate that NaTaO3 is a promising material for UV photocatalytic water splitting, UV optoelectronic devices, UV-transparent optical coatings, Bragg reflectors and as a dopable host matrix for visible-light photocatalysis.

Enhanced antibacterial performance of ZnO-Co3O4 nanocomposites for effective pathogenic bacteria control
The rise of antibiotic resistance necessitates the development of advanced antibacterial agents. Here, a ZnO-Co3O4 nanocomposite with varying concentrations is synthesized via the sol-gel method. The structural and morphological features of the as-synthesized nanocomposite are characterized using X-ray diffraction, scanning electron microscopy, and Fourier-transform infrared spectroscopy techniques. The composite design enhances antibacterial performance compared to single oxides. The results revealed that ZnO-Co3O4 nanocomposites exhibit concentration-dependent morphology and antibacterial activity. Notably, ZnO-Co3O4 nanocomposites demonstrated superior antibacterial activity compared to pure ZnO. The addition of cobalt oxide decreased the size of the nanoparticles, thereby enhancing their antibacterial activity, particularly against Gram-positive bacteria, compared to Gram-negative bacteria. This enhanced activity is attributed to the increased production of reactive oxygen species and the improved penetration capability of the nanocomposite.

Numerical and experimental investigations of the crushing behavior of thin-walled multi-cellular steel cylinders
The quasi-static axial crushing behavior of an all-metal corrugated sandwich cylindrical shell is investigated experimentally and numerically. The structure consists of inner and outer thin-walled steel shells connected by a trapezoidal corrugated steel core, fabricated using a low-cost method without adhesives. Quasi-static compression tests were conducted on three ST37 steel specimens and validated using finite element simulations accounting for material plasticity and large deformations. The results show that the corrugated sandwich cylindrical shells deform through stable progressive local buckling. Compared with monolithic cylinders of similar mass, the proposed design exhibits significantly higher energy absorption, reaching up to approximately 1.5 times improvement. Parametric analyses reveal that increasing the number of corrugated units and optimizing the core-to-shell thickness ratio markedly enhance crushing efficiency while reducing peak crushing force. The proposed all-metal corrugated sandwich cylindrical shell provides an efficient, manufacturable solution for lightweight energy-absorbing structures in automotive, marine, and protective engineering applications.

Nonlocal mesomechanics of elastic-plastic transition
A unified description of the behavior of condensed media over a wide range of external impact durations and strain rates has been developed using a nonlocal theory of nonequilibrium transport processes, based on rigorous results of nonequilibrium statistical mechanics. The constructed nonlocal momentum transfer model encompasses the elastic-plastic transition induced by a short impact on a solid material, quasi-static loading, and the transition to hydrodynamic flow of a liquid medium. The first moments of the spatiotemporal correlation functions in the integral expression for the momentum flux determine the sizes of the mesoscopic carriers of plastic deformation in high-rate processes. During the thermodynamic evolution of the medium's structure, an internal control loop emerges that reduces irreversible losses in the system and predicts its most probable future behavior.

Prediction of properties of high-performance concrete containing glass fibers and minibar basalt using AI-based criteria
The aim of the study is to predict compressive strength and the failure mechanism of concrete cubes considering the Tresca criterion for high-performance concrete reinforced with glass fibers and minibar basalt. The method of research includes experimental compression tests on 100 mm cubes at curing ages of 7, 14 and 28 days soft computing techniques such as linear regression ridge regression and polynomial regression implemented in Python using scikit-learn artificial neural networks developed with Python and NumPy to visualize cracks and failure patterns as pixels as well as the incorporation of the Mohr-Coulomb and Tresca criteria to model the plastic zone and pyramidal failure shape. The results demonstrate that polynomial regression provides the highest predictive accuracy for compressive strength achieving R2 values greater than 0.99 for minibar basalt fiber-reinforced high-performance concrete and greater than 0.93 for glass fiber-reinforced high-performance concrete while the artificial neural networks successfully identify and predict crack locations failure degree and pyramidal failure shapes and overall model performance is validated by a coefficient of determination greater than 0.97 with mean absolute error greater than 2.1 and root mean square error greater than 16.99 confirming strong agreement between experimental and predicted values. Therefore, the research's novelty lies in its use of artificial intelligence by taking into account the TRESCA criteria to precisely predict the properties of high-performance concrete and to understand the impact of its input factors, streamlining the process and providing useful tools for the real-world application of the model's capabilities in the field of civil engineering.

The fuzzy logic analysis as criterion of hot rolled stainless steel destruction caused by corrosion
This study explores how predictive modeling can be used to assess and improve the corrosion resistance of steels by modifying metal forming parameters. Traditional statistical methods often fall short when evaluating corrosion resistance due to the stochastic nature of structural transformations during plastic deformation. To address this, we applied Fuzzy Logic within the MATLAB environment to uncover the non-linear dynamics between hot rolling conditions, microstructure, and corrosion rates. Drawing on experimental data from AISI 321 and S32750 steels, we constructed Mamdani-based mathematical models to visualize how deformation levels, pass counts, and microalloying affect intergranular and pitting corrosion. Subsequent validation of the models revealed a key finding: high predictive accuracy requires more than just processing parameters and basic structural data. It is critically important to include mechanical properties, namely yield strength and hardness, in the input dataset, since a material's resistance to corrosion-driven degradation is fundamentally tied to its stress-strain state.
