摘要

A simplified model was applied for the precipitation behaviour of Fe and Si contained inrncommercial purity aluminium. The model was basically constructed with the nucleation andrngrowth theory. The temperature-time-precipitation curves for Al3Fe, α -AlFeSi andrnelemental Si were mainly described in this paper. The present simplified modelrnquantitatively explained the experimental results concerning TTP curves and a slightrnvariation of the content of Fe in solid solution and the total amounts of Fe or Si that existedrnas constituents and precipitates in commercial purity aluminium.
