Anelastic Behavior of Hydrogenated Amorphous Metals

Abstract

The long-range Gorsky effect and a short-range reorientation relaxation represent two valuable and complementary tools for the study of hydrogen in amorphous metals. This paper deals primarily with understanding the reorientation relaxation as a Snoek-type effect in an amorphous, rather than a crystalline, host. Results on the concentration and temperature dependence of the relaxation strengths are given to clarify the issues involved. A new model of the reorientation relaxation is presented, in which site-pair energy correlation and H-H repulsion are introduced and found to play key roles in explaining the observed behavior. © 1989, R.
