抄録
The coarsening of Al3Sc precipitates in an Al–1 mass%Mg–0.27 mass%Sc alloy aged at 573 K has been examined using a model developed by Kuehmann and Voorhees. The average size of Al3Sc precipitates was evaluated by transmission electron microscopy and electrical resistivity was employed to measure the Sc concentration in the matrix. Kinetic analyses revealed that before the onset of a coarsening stage, there exist mixed stages of nucleation and growth and of growth and coarsening. The coherent Al/Al3Sc interface energy γ is estimated as 0.23 Jm−2 from data on coarsening alone. The transition from a coherent interface to a semi-coherent interface caused no change in γ.
