Abstract
The oxygen dissolution in metallic zirconium has been investigated by electrochemical and X-ray techniques, The mechanism of the zirconium o xidation process is proposed. It is shown that during the first stage of the process, oxygen dissolves in the metal matrix acting as an elec tron donor. The region of oxygen solid solutions in zirconium reaches 25 at. % oxygen. After oxygen saturation of the metal surface the seco nd stage starts; zirconium oxides form.
