Coarsening behavior of Al3Sc precipitates in an Al-Mg-Sc alloy

The coarsening of Al3Sc precipitates in an Al–1 mass%Mg–0.27 mass%Sc alloy aged at 673 to 748 K has been studied by measuring both the precipitate size by transmission electron microscopy (TEM) and the Sc concentration in the Al matrix by electrical resistivity measurements. The growth and coarsening of Al3Sc precipitates occur concurrently prior to the beginning of coarsening. The Al3Sc precipitates grow more
