Abstract
The effect of long-time homogenization and aging on the formation of disperse β′ phase particles and β phase particles has been analyzed. Alloys solidified with the cooling rate of ∼10− 1 °C/s (Al–10%Mg and Al–10%Mg–0.1%Sc) and alloys melted by centrifugal casting with the cooling rate of ∼ 103 °C/s (Al–10%Mg) were chosen for comparative analysis. А significant heterogeneity of the distribution of the strengthening β′-phase after aging is observed in Al–10%Mg alloys obtained by the ingot technology. The greatest hardening up to 100% is achieved after using the centrifugal casting due to the formation of the β′-phase during aging.
