Abstract

It is shown that in analysing DSC data of precipitation reactions in Al–1.12Mg2Si–0.35Si, Al–1.07Mg2Si–0.33Cu and Al–1.0Mg2Si–0.5Ag alloys in work by Gaber et al., accurate values for the activation energies are obtained by applying the method derived by the present author (the Type B-1.92 method). Values obtained from other analysis methods reported by Gaber et al. are less accurate. Averaging activation energies obtained by different methods introduces inaccuracies and obscures these inaccuracies, especially if the set of methods applied includes highly inaccurate ones, such as the Ozawa and Takhor methods.
