Upon aging at 300-450 °C, nanosize, coherent Al 3 (Sc 1Àx Ti x ) precipitates are formed in pure aluminum micro-alloyed with 0.06 at.% Sc and 0.06 at.% Ti. The outstanding coarsening resistance of these precipitates at these elevated temperatures (61-77% of the melting temperature of aluminum) is ex
