Isothermal measuring curves of a series of Al‐4.5 at.% Zn‐ X at.% Mg ( X = 0.2, 0.5, 1.0, 1.5, 2.25, 3.0) were evaluated analytically by means of the Johnson‐Mehl‐Avrami equation. Itturned out to be possible to fit the curves completely only by assumption of two process stages. The course of the parameters obtained their dependence upon the Mg content is interpreted by means of suitable model assumptions.
