The studied new BN diamond-like phases exhibit high mechanical strength, comparable to the theoretical tensile strength of diamond, cubic BN, and wurtzite BN. For LA phases, a dependence of strength on the structure density is observed: the higher the structure density, the higher the strength.

It has been established that ultrasonic-assisted WEBAM conducted at a US power of 350 W alloy interferes with the epitaxial growth of prior columnar β-Ti grains and reduces the degree of crystallographic texturing. Despite there still being some prior elongated β-Ti grains, their longitudinal and transverse dimensions, as well as the thickness of the α-laths significantly reduced. It has been experimentally shown that the application of ultrasound to the substrate does not allow to completely eliminate the anisotropy of the mechanical properties. The strength characteristics increased on average by 50 MPa only in the zone directly adjacent to the ultrasound source, while in the upper layers of the product, they are on average 30 MPa lower than in control samples manufactured without the use of ultrasound.

This work examines phonon thermal conductivity in ultrathin cobalt films via molecular dynamics, revealing how thickness, temperature, and crystal phase – particularly the HCP–FCC transition near 700 K – govern heat transport. A twofold drop at 1.8 nm and an anomalous rise at sub-nanometer scales in the FCC phase highlight the complex interplay between size effects and structural transformations, offering practical guidance for thermal management in cobalt-based nanoelectronics.

Density functional theory calculations demonstrate that hydrogen atoms in FCC titanium preferentially occupy tetrahedral interstitial sites. The most stable configurations are formed when H–H distances are maximized along the body diagonal of the tetrahedral sublattice, resulting in ordered titanium hydrides.

Hot extrusion and recrystallization annealing of the as-cast Ni50Mn18.5Ga25Cu6.5 alloy transform its microcracked structure into an equiaxed coarse-grained one. This structural modification preserves the coupled magnetostructural phase transition and only slightly reduces the peak value of the magnetocaloric effect from 0.27 K to 0.25 K.
