    The effect of temperature factor during heavy ion irradiation on structural disordering of SiC ceramics by Kymbat M. Tynyshbayeva, Artem L. Kozlovskiy

    Published 2025-02-01
    “…The assessment results of changes in the electron density distribution contingent upon the irradiation temperature for both types of ion irradiation showed a direct correlation between the irradiation temperature growth and the electron density anisotropic distortion caused by the deformation of chemical bonds. In turn, the combination of the effects of thermal heating and ionization processes causes deformation distortion of chemical bonds, which is most pronounced at high irradiation temperatures, for which thermal expansion of the crystal lattice and accelerated diffusion of vacancy defects play a key role in disordering.…”
