The changes in the potential and vibrational energies upon the formation of vacancies in the oxygen-alloyed cores of crystallite-conjugation regions in polycrystals of d transition metals Cr, Cu and Ir were determined. The potential energy increased upon the formation of vacancies (upon the formation of complexes of vacancies with oxygen atoms) in the oxygen-alloyed cores of crystallite-conjugation regions in the polycrystalline Cr, Cu, and Ir. However, the vibrational energy decreased upon the formation of vacancies in the oxygen-alloyed cores of crystallite-conjugation regions in these polycrystals, as in the oxygen-alloyed cores of crystallite-conjugation regions in polycrystals of the 4d and 5d transition body-centred cubic metals Mo, Ta, and W. The volume of the oxygen-alloyed cores of crystallite-conjugation regions in polycrystals of Cr, Cu, and Ir decreased upon the formation of vacancies. The changes in the interatomic interactions and dynamic properties in the regions of vacancy localization in the oxygen-alloyed cores of crystallite-conjugation regions coincided with analogous changes introduced into the lattices of metals by split interstitials.
