This study examined the influence of substrate temperature and ratio iron copper vapor flow on structural state Fe–Cu vacuum condensates. XRD patterns condensates deposited under specific electron beam physical deposition process parameters revealed peaks corresponding to either bcc or bcc+fcc phases. Analysis lattice parameter single structure indicates that only a portion atoms dissolve in bcc-Fe lattice, while undissolved form bcc-Cu inclusions are coherent with lattice. A model for...
Досліджено механічні і дисипативні властивості вакуумних конденсатів високоентропійних сплавів системи Cr-Fe-Co-Ni-Cu, отриманих методом високошвидкісного електронно-променевого осадження з парової фази у вакуумі, залежно від їх структурно-фазового стану.Показано, що в інтервалі температур 923…1025 К має місце перехід однофазного (ГЦК) структурного стану конденсата двофазний (ГЦК1 + ГЦК2).Встановлено, CrFeCoNiCu, електронно-променевим осадженням фази, суттєво залежать стану.Однофазні...
The nanoporous structure of nickel vacuum condensates produced by the EB PVD method was investigated. nanoscale pores were analyzed using small-angle X-ray scattering (SAXS) and scanning electron microscopy (SEM) techniques. It observed that set these nanopores can be considered a bimodal system with characteristic sizes approximately 1–3 nm 20–30 nm. is assumed smaller form as result coalescence individual vacancies into clusters during vapour phase deposition in vacuum. These have close to...
An influence of the grain size quasicrystalline Al-Cu-Fe materials (QCs) on their damping capacity at alternate loading has been investigated in strain amplitude range 1.25×10−4 and temperature 20–350°C. It established that nanometer-sized QCs heating is essentially higher than submicron-sized ones. Logarithmic decrement found to increase progressively whole as temperatures go some threshold value. Possible mechanisms dissipation mechanical energy elevated are discussed.
The conditions of the appearance one-dimensionally disordered long-period structures in alloys are studied. It is shown that role kinetic factors and electronic states formation essential. [Russian Text Ignored].
