摘要

The previously presented Classical Nucleation and Growth model (ClaNG) of precipitationrnin aluminum alloys [1] was extended to describe simultaneous nucleation, growth andrncoarsening of several types of spherical precipitates for different heat treatments. Itrnpredicts the precipitation kinetics during annealing 1xxx, 5xxx and in particluar 3xxx seriesrnalloys. In order to describe the mentioned alloy systems with respect to phase diagramrnand latent heat over the whole range of temperature and concentrations, the model utilizesrnthe commercial Gibbs energy minimizer ChemApp (GTT Technologies, Herzogenrath,rnGermany) [2] and thermodynamic databases which enables to calculate the chemicalrndriving forces and equilibrium compositions. The main advantage of this strategy is nornrestriction to a special alloy system.
