This work deals with the oxidation kinetics of the MA 956 superalloy in the temperature range of 800-1,200°C for up to 200 h exposure. During oxidation the alloy develops a fine, compact and very well adhered α-alumina layer, the thickness of which increases with increasing time and temperature. The oxidation kinetics obeys a subparabolic type behaviour. The scale growth seems to occur by two different oxidation mechanisms; above 1,050°C, the oxidation process would be controlled by α-alumina, and below 900°C by γ-alumina.
