The various phases and the respective ranges of their existence were determined during continuous cooling from temperatures close below the solidus line to R.T. with a rate of 2 K min −1 as well as during the subsequent heating in few AlZn(40 wt.%)–Mg(X) alloys (X = 0; 0.5; 1.0; and 3.0 wt.%) by means of X‐ray phase‐analysis, small angle X‐ray scattering, differential thermo‐analysis, optical microscopy, and X‐ray micro‐analysis. The most striking features are that even addition of only 0.5 wt.% Mg cause the formation of precursors of the MgZn 2 equilibrium phase few degrees below the solidus line.
