摘要：

Scanning electron microscope observations of Ni samples annealed after recovery from high temperature heat treatment in the hydride phase showed the presence of numerous holes 20-200 nm in size. From various features of the holes they are identified as voids formed by agglomeration of supersaturated vacancies (about 5 at.% in concentration) which have diffused from the surface to the interior of the sample during heat treatment.
