For the aged aluminum alloys which generally contain disc/plate-shaped or rod/needle-shaped precipitates, a model has been established, from the viewpoints of thermodynamics, kinetics and strengthening theory, to relate quantitatively the yield strength to the size, volume fraction and aspect ratio of precipitates which all were analytical associated with the chemical compositions of alloys, aging temperature and aging time. This model has been experimentally proved to well predict the variation of yield strength with the evolution of disc/plate-shaped or rod/needle-shaped precipitates for present Al-4. 62wt% Cu-0.65wt% Mg alloy aged at 513K and Al-1. 12wt% Mg0.57wt% Si alloy aged at 463K, respectively, and the yield strengths simulated by this model were also found to be in well agreement with previously measured values for a series of aged Al-Cu binary alloys, AA6061 and Al-Zn-Mg alloys.
