Parameters of Interaction with Vacancies in Tungsten of Homovalent Atomic Probes from the VIB and VIIB Groups of the Periodic Table

Abstract:

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.
