【 摘 要 】

Investigation results of surface oxide scale features during the oxidation of V-Cr- Ta-Zr alloy in air are presented. Intensive oxidation processes in time interval under study lead to an increase in the scale thickness. Oxide scale structure is characterized by open porosity formed as a result of sticking together of small flakes of plate-shaped oxides (V2O5).
