Atomic Defects in Metals · V

Abstract

This chapter discusses the properties and atomic defects in vanadium (V). Vanadium belongs together with Nb and Ta to the group V B transition metals, which are known for a strong tendency to solve the light elements H, O, N, C on interstitial sites (impurity interstitials). Resistivity recovery has been studied for the following modes of defect creation: 1) electron irradiation, 2) thermal- and fission neutron irradiations, 3) plastic deformation near room temperature, 4) quenching from near the melting point, and 5) positron annihilation. For vanadium, the intrinsic stage III is not very certain to locate, due to the absence of systematic investigations on high-purity specimens. Comparing the recovery curves for V, Nb and Ta, it appears reasonable to follow and to locate stage III at 170K for n-irradiations. Properties of Frenkel defects (FD), self-interstitial atoms (SIA), and vacancies (V) in vanadium are tabulated. The chapter also presents the data of vacancy-solute atom interaction. Resistivity recovery of vanadium following thermal- and fission-neutron damage, resistivity recovery in vanadium between 3.8 and 6.0 K following thermal-neutron irradiation, resistivity recovery of vanadium following fast-neutron irradiation near liquid helium temperature, isochronal resistivity-recovery curve and differential curve of vanadium following fast-neutron irradiation, resistivity recovery of vanadium following plastic deformation near room temperature, and resistivity recovery of vanadium quenched from near the melting point combined with Snoek-peak control of O, N, C are also illustrated.
