Ultrasonics studies of point defects in iron, aluminum-lithium, and gallium arsenide
Abstract
dc:descriptionThe ultrasonics studies undertaken in this work illustrate the applicability of ultrasonics to a broad variety of problems. In the case of Fe, the objective is to measure the production and annealing of the diaelastic effect of self-interstitials in Fe. Frenkel Pairs created by 2.3 MeV electron bombardment cause the shear moduli, \rm C\sp\prime and C\sb{44}, to soften by (\rm-27\pm2)\% and (-17\pm4)\%, per at.% pair. The magnitudes are of the same order as for Cu, but the observed anisotropy matches that detected in Mo, the only other bcc metal tested.
