Figure 5. Calculated phase diagrams of the Al-Fe-Mg-Si system: (A) quasi-ternary isothermal section with fixed iron content of 0.3 wt% at 550 °C. The Mg/Si atomic ratios of red and blue dotted lines are 2:1 and 1:1, respectively. The red cross is the composition with the same contents of Mg and Si as the finally designed alloy. (B) Vertical section of Al-1.05Mg-0.85Si-xFe (in wt%). Figure reproduced from Ref.^[167] with permission from Elsevier.
