Abstract

High spatial resolution X-ray microanalysis of thin foils, in a transmission electron microscope, was applied to determine solute content profiles existing across the α lamellae formed by discontinuous precipitation (DP) in an Al-22 at. % Zn alloy. This technique, combined with the in situ observation of the kinetics of the process, allowed us to treat the DP reaction as a local phenomenon. The calculated diffusivity at a moving reaction front was found to be in good agreement with the data on diffusion at a stationary grain boundary and, in this way, the discrepancies resulting from the consideration of the DP as a global reaction were eliminated
