  • Grain-Boundary Diffusion of Hydrogen Atoms in the α-Iron 
    Teus, S.M.; Gavriljuk, V.G. (Металлофизика и новейшие технологии, 2014)
    Grain boundary diffusion of hydrogen atoms in the α-iron is analysed based on the theoretical modelling. By means of molecular-dynamics simulation of hydrogen-atoms’ migration in selected special grain boundaries with ...
  • Hydrogen Grain Boundary Segregation and Migration in the Alpha-Iron 
    Gavriljuk, V.G.; Teus, S.M. (Металлофизика и новейшие технологии, 2017)
    Based on the difference in diffusion mechanisms of substitutional and interstitial atoms and using molecular dynamics simulation of hydrogen migration, it is shown that accelerated hydrogen flux in the polycrystalline iron ...
  • Hydrogen in Nickel: Hydride or Miscibility Gap? 
    Movchan, D.N.; Teus, S.M.; Mogilny, G.S.; Gavriljuk, V.G. (Металлофизика и новейшие технологии, 2013)
    Using low temperature X-ray diffraction, the phase transformations in the hydrogen-saturated nickel are studied. At the hydrogen degassing, its content in nickel decreases down to H/M ratio of about 0.65. The further ...
  • Hydrogen Mobility and Its Interaction with Dislocations in Nickel-Based Inconel 718 Alloy 
    Teus, S.M. (Металлофизика и новейшие технологии, 2017)
    The hydrogen effects in the nickel-based alloy Inconel 718 are studied using the mechanical spectroscopy and mechanical tests. The enthalpies of hydrogen-atoms’ migration and hydrogen–dislocations binding as well as the ...
  • Mechanism of Embrittlement of Metals by Surface-Active Elements 
    Teus, S.M.; Shanina, B.D.; Konchits, A.A.; Mogilny, G.S.; Gavriljuk, V.G. (Металлофизика и новейшие технологии, 2018)
    The nature of mechanical degradation of metals caused by surface-active elements is studied based on the effects of iodine and gallium in austenitic steels and using abinitio calculations and experimental measurements of ...
  • Precipitation Reactions in Nickel—Hydrogen System: ab initio Study 
    Teus, S.M. (Металлофизика и новейшие технологии, 2016)
    A type of precipitation reactions in the nickel—hydrogen system is studied by means of first-principle atomic calculations. The concentration dependence of solution enthalpy is calculated, and its second derivative is shown ...
