Anelastic relaxation due to OH pairs in NbZr alloys
(Elsevier B.V., 1994-09-01)
In the last 30 years several studies have been made to understand the relaxation mechanisms of the hydrogen atoms present in transition metals and their alloys. In this work, we observed the stress-induced ordering of ...
