The effect of beryllium addition on magnesium and magnesium-aluminium alloys were studied by measurement of weight increase accompanied by oxidation process in dry oxygen and with electron diffraction of oxide films formed. In the temperature range of 440°-650°C, so-called protective and coherent films were formed on magnesium alloys containing beryllium.It was shown that 0.002-0.003% beryllium addition supresses effectively the progress of oxidation of magnesium-aluminium alloys.As to some films which showed protective behaviour on oxidation of magnesium alloys, the presence of BeO in oxide films was found by electron diffraction analysis. It was presumed that the oxide film containing BeO controlles the oxidation of magnesium alloys.
