Title: Symmetry lowering of lattice defects due to anharmonic interatomic forces

Abstract

From fifth international corference on internal friction and ultrasonic attenuation in crystalline solids; Aachen, Germany (27 Aug Interstitials produced by fast-particle irradiation of metals have previously shown to produce a significant reduction of the elastic moduli. An atomic model is proposed that explains the observed effect of the interstitials. It is shown that anharmonic interatomic forces may lead to a lowering of the symmetry of the atomic configuration around the interstitials. The deformability of the interstitials is also taken into account. (GE)
