摘要

A physical model for predicting precipitation reactions in aluminium alloys has beenrndeveloped at Corus Research, Development & Technology. The model is based on thernclassical nucleation theory and diffusion-controlled growth. In this work the model was appliedrnto predicting Al3Zr precipitation in AA7050 alloy. To determine parameters in the model,rnsamples taken from a DC-cast AA7050 ingot, were isothermally annealed at differentrntemperatures. The number density and the size of Al3Zr-precipitates in the annealed samplesrnwere measured using transmission electron microscopy. A good agreement between thernmeasured microstructural parameters and these predicted by the model was found.
