Parameters of Interaction with Vacancies in Tungsten of Homovalent Atomic Probes from the VIB and VIIB Groups of the Periodic Table
The Volume Diffusion of Homovalent Atomic Probes (APs) from the VIB Group of the Periodic Table of Elements (PTE): Сr, Mo, W and from the VIIB Group of the PTE: Mn, Tc, Re in W Single Crystals Has Been Studied by Using Secondary Ion Mass Spectrometry (SIMS) and Radiometric Layer-by-Layer Analysis. the Enthalpies Q of the Bulk Diffusion of Homovalent APS from the VIB Group (Сr, Mo, W) and from the VIIB Group (Mn, Tc, Re) of PTA Increase with the Growth of N Numbers of their Periods in each Group whereas the Relaxation Volumes of the Complexes “va-Cancies- VIB, VIIB Aps” in the W Lattice Do Not Differ Practically. the Detected Change of En-Thalpies Q Is Conditioned by the Difference in Magnetic Moments of Homovalent Aps from the VIB and VIIB Groups of PTA in Complexes with Vacancies in the W Lattice.
