Abstract
The morphology and composition of the oxide film formed under various oxidation conditions on a 1.2% aluminum-magnesium alloy have been studied using electron microscopy and diffraction. Below 350° C the oxide film formed is highly protective and amorphous, while above this temperature the oxide becomes nonprotective. Initially, at temperatures above 350°C, the oxide film consists of only alumina, then with increasing time it contains first MgO, then MgO together with MgAl2O4, and finally it is entirely converted to MgAl2O4.
