Al-Nb composites demonstrate a considerable dependence of tensile strength on HPT straining which almost doubled upon the increase of torsional straining from 30 to 100 rotations of HPT anvil and reached 530 MPa. Annealing resulted in an increase in ductility up to ~12% with a slight decrease in tensile strength.

Carbide/binder grain boundaries in a FIB lamella prepared from the WC-Co-Re cemented carbide were examined by high-angle annular dark field scanning transmission electron microscopy and energy dispersive X-ray spectroscopy at a high resolution. Rhenium was found to segregate at the grain boundaries forming complexions of 2 to 3 atomic monolayers, which presumably consist of mixed W-Re carbide.

The thermokinetics of shape recovery after bending of Ni-rich titanium nickelide was studied. Loading–unloading procedure was carried out in various phase states using isothermal and non-isothermal modes varying loading strain. The two-stage character of shape recovery under heating is revealed; the hypothesis of its origin is suggested.

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.

The force change depending on the deflection during DWTT
Curve No. 2 - the notch is perpendicular to the direction of vibration (WD); Curve No. 3 - the notch is parallel to the direction of vibration (WD).
A characteristic feature of the deformation diagrams for specimens with the parallel notch is the presence of two local maxima. This contrasts with the force change curve for the perpendicular notch specimens.
