The lattice constants of primary solid solutions of indium, aluminum, and cadmium in magnesium have been determined as a function of composition. A sharp change in (c/a) has been found only for magnesium-indium. The linearity of the (c/a) vs concentration curve for magnesium-aluminum has suggested that electron zone overlap does not necessarily lead to axial ratio anomalies and that changes in short-range order may be needed to explain such anomalies.
