Abstract
A model of precipitation hardening of an Al – Mg – Si alloy due to precipitation of several phases formed under different aging conditions is presented. The diameters of the precipitated particles and their relative contents are determined by the method of thermodynamic simulation. The characteristics of the precipitated phases are allowed for, which raises the prediction accuracy. The rate of the precipitation of the β- and β′-phases is shown to increase with the aging time, and the rate of growth of their particles is shown to increase with the temperature.
