SNOEK AND ZENER RELAXATION EFFECTS IN METAL HYDRIDESF.M. MAZZOLAI
Department of Physics, Perugia University, I-06100 Perugia, Italy
The main features of anelastic relaxations observed in H(D) loaded pure metals or alloys are reviewed and a discussion is made of results in the literature concerning the H(D) Snoek and Zener effects. As a result of this review it is found that so far the Snoek effect has probably only been detected in pure V and in some Nb and Ti (β form) based alloys. The Zener effect appears to be a common feature of al1 the non stoichiometric hydrides.
