During heat‐treatment of Mg‐containing Al‐based alloys, the Mg concentration changes considerably. As compared to the pure material significant surface corrosion is observed for the air heattreated alloy. In vacuum heat treatment the Mg content of the surface layer increases considerably. Initially metallic Mg is detected on the surface which, however, becomes oxidized later on. On the basis of the investigations one has to assume that the process is not a simple diffusion mechanism only. A new conception is formed for the process according to which it is controlled by the breaking up of the Al2O3 barrier layer by Mg.

A special self‐absorption effect of the Mg‐enriched surface of AlMg alloys is described for Al L2,3 emission spectra. In the light of these new considerations, the evaluation of the experimental data have to be modified and the earlier results in this field should be reevaluated. The problem is more general than this actual one, focusing attention on the complexity of the evaluation of emission spectra of alloys and compounds which have emission spectra, of the components nearby or overlapping each other.
