Abstract
The discontinuous dissolution reaction has been analyzed in an Al-22 at. % Zn alloy. A simulation method based on the Zięba-Pawłowski equation has been used to determine the solute concentration profiles expected to form behind the receding cell boundary for various initial values of the solute concentration in the α lamella at the α/β interface as well as the solute concentration in the newly formed α∼ solid solution at the tip of the β lamella. A criterion for the applicability of the Zięba-Pawłowski model has been formulated. The simulated profiles are in a very good agreement with the experimental ones obtained by using a special procedure involving in situ observation and high spatial X-ray measurements in a transmission electron microscope.
