Steady state isotropic optimal superplastic deformation in 175 materials systems of different classes studied can be represented by the equation 8 in the main text

Tantalum-containing film with superhard inclusions

The paper investigates the effect of long-term operation at a temperature of 515 °C on the structure and properties of steel grade 08Cr16Ni11Mo3. As a result of the study, it was found that during operation at a temperature of 515 °C for 195,000 hours in steel grade 08Cr16Ni11Mo3, the structure changes with the formation of secondary phases, initiated by the release of elements with limited solubility from the supersaturated solid solution. A change in the phase composition during heat aging leads to embrittlement of steel - a decrease in plasticity.

It was found by molecular dynamics that the deposition of hydrogenated and dehydrogenated carbon atoms on defect-free graphene depends on the degree of hydrogenation of carbon atoms.

Adsorption of lithium on a carbon nanotube with a vacancy defect.

Protective coatings that improve the corrosion resistance of the E125 zirconium alloy under conditions of the combined effect of a hydrogen-containing medium and friction wear have been investigated.

LPBF of multiple sieved powder of Co-28 wt.% Cr-6 wt.% Mo leads to the formation of samples with inclusions of Cr and Mo within the bulk. Increasing the duration of annealing post-treatment leads to the initiation of diffusion processes, which, in its turn, leads to the gradual dissolution of Cr and Mo inclusiuons

Possibility of using silver nanoparticles (Ag NPs) as additive for silicone elastomers as internal heating agent for microwave radiation assisted local curing is experimentally investigated. The obtained PDMS/AgNP composite materials acquired a significantly higher work of adhesion to glass, a lower viscoelastic modulus and slightly higher wettability. With time of microwave treatment and consequently cross-linking of the material those parameters head towards or approach those of the stock PDMS material.

After rotary forging at 700°°C, the alloy manifests the best combination of the structural, mechanical, and functional characteristics. In this state, the long-length bar stock demonstrates a homogeneous grain structure with a certain fraction of a dynamically polygonized substructure of β-phase, a satisfactory strength (UTS=580 MPa), a low Young’s modulus (E=35 GPa), high difference between dislocation and phase yield strength (Δσ = 280 MPa), and a relatively large amount of superelastic recovery strain (εrSEmax=3.12%).

Informative picture demonstrates abnormal strain rate dependence of peak strain in the range of 1 to 100 s-1. The presented structures comply with the loading diagrams.

Extensive hydrogen desorption, which is continued and not ceased even after 24 hours after pre-exposure of ZK60 samples in the corrosion solution, is the evidence for the corrosion reaction occurring under the layer of corrosion products.
