## Abstract Three types of alloys have been studied, Alโ€“Mg, Alโ€“Zn, and Alโ€“Si. The first type of alloys include Alโ€“11.1 wt% Mg, Alโ€“4.5 at% Mg and Alโ€“2.5 at% Mg. The second type includes low Zn contents at 1.3% and 3.2% (at%). The third type includes alloys with Si contents of 1.37%, 2.83% and 6.81%
