Spontaneous recombination volumes of Frenkel defects in neutron-irradiated non-fcc metals

Abstract

Production and production-rate curves for the non-fcc metals Fe, Mo, Ta, W, Zr, and Sn are obtained by electrical-resistivity measurements taken at 4.6 K during reactor neutron irradiations. The saturation concentration of Frenkel defects, ${c}_{s}$, and the recombination volume ${v}_{\mathrm{o}}$ are evaluated. A parabolic relation between the spontaneous recombination volume ${v}_{0}$ and the compressibility $\ensuremath{\kappa}$ for a series of bcc metals is found.
