Recent results on the effect of the nanocrystalline state on the mechanical, thermal, and
magnetic properties and microscopic structure of metals and solid-phase compounds are …

Рассмотрены последние результаты изучения влияния нанокристаллического
состояния на микроструктуру и механические, теплофизические, магнитные свойства …

A new, versatile method of calculating positron states in solids is described. The main
purpose is to develop a practical scheme accurate enough to reliably predict annihilation …

We present evidence of homogenization of atomic diffusion properties caused by C and N
interstitials in an equiatomic single-phase high entropy alloy (FeMnNiCoCr). This …

Quantum-mechanical calculations are used to determine the temperature dependence of
the Gibbs energy of vacancy formation in nickel. Existing data reveal a discrepancy between …

Nanocrystalline Ni Fe 2 O 4 particles were synthesized in a Si O 2 matrix and were
characterized by x-ray diffraction and TEM observations. Positron lifetimes in these samples …

We consider the specific problem of the influence of an inhomogeneous distribution of
defects in solids on positron annihilation characteristics. In detail, we investigate the effect of …

Electron-irradiated high-purity α-iron doped with various amounts of interstitial carbon
impurities has been studied by positron-lifetime measurements. It is shown that during …

We investigate the influence of microstructure (dislocations, and grain and subgrain
boundaries) on the sintering process in compacts of electrolytic and spherical copper …

In the past six years perturbed angular correlations (PAC) and perturbed angular distribution
(PAD) of γ rays have been widely applied to study the migration, trapping, and clustering of …
