  • spark plasma sintering for high speed Diffusion bonding of the ultrafine grained near α ti 5al 2v alloy with high strength and corrosion resistance for nuclear engineering
    Journal of Materials Science, 2019
    Co-Authors: V N Chuvildeev, A. V. Nokhrin, V I Kopylov, M S Boldin, Mikhail Mikhaylovich Vostokov, Mikhail Yuryevich Gryaznov, Nataliya Yurevna Tabachkova, P V Tryaev
    Abstract:

    The paper demonstrates the prospects of spark plasma sintering (SPS) for the high-speed Diffusion bonding of the high-strength ultrafine-grained (UFG) near-α Ti–5Al–2V alloy. The effect of increased Diffusion bonding intensity in the UFG Ti alloys is discussed also. The bonding areas of the UFG near-α Ti–5Al–2V alloy obtained by SPS are featured by high density, strength, and corrosion resistance. The rate of bonding in the UFG alloys has been shown to depend on the heating rate non-monotonously (with a pronounced maximum). At the stage of continuous heating and isothermic holding, the bonding kinetics was found to be determined by the exponential creep rate, the intensity of which in the coarse-grained alloys is limited by the Diffusion rate in the crystal lattice α-Ti. In the UFG alloy, the exponential creep processes associated with gliding and climb of dislocations, the Activation Energy of which corresponds to the Diffusion Activation Energy in the lattice dislocation nuclei, may take place simultaneously with the grain boundary sliding and Coble creep, the Activation Energy of which corresponds to the grain boundary Diffusion Activation Energy.

  • A theoretical model of grain boundary self-Diffusion in metals with phase transitions (case study into titanium and zirconium)
    Physica B: Condensed Matter, 2018
    Co-Authors: Alexandra V. Semenycheva, V. N. Chuvil’deev, A. V. Nokhrin
    Abstract:

    Abstract The paper offers a model describing the process of grain boundary self-Diffusion in metals with phase transitions in the solid state. The model is based on ideas and approaches found in the theory of non-equilibrium grain boundaries. The range of application of basic relations contained in this theory is shown to expand, as they can be used to calculate the parameters of grain boundary self-Diffusion in high-temperature and low-temperature phases of metals with a phase transition. The model constructed is used to calculate grain boundary self-Diffusion Activation Energy in titanium and zirconium and an explanation is provided as to their abnormally low values in the low-temperature phase. The values of grain boundary self-Diffusion Activation Energy are in good agreement with the experiment.
