SNOEK AND ZENER RELAXATION EFFECTS IN METAL HYDRIDES

Abstract
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.
