Influence of predeformation and agEing of an Al–Zn–Mg alloy—II. Modeling of precipitation kinetics and yield stress

We present a model for precipitation kinetics integrating nucleation growth and coarsening. This model allows the description of competitive kinetics of heterogenous and homogeneous precipitation. The precipitation model is coupled to a model for structural hardening predicting the yield stress. This structural hardening model includes the possibility of taking into account the distribution of precipitate size and strength. The model is applied...
