Phase Relations in the A356 Alloy: Experimental Study and Thermodynamic Calculations


  • This work was financially supported by the German Research Foundation (DFG) in frame of the subproject A03 within the Collaborative Research Centre SFB 920.


A thermodynamic database of the Al-rich side of the Al–Fe–Mg–Si system was derived and it was used to calculate phase transitions and solidification behavior of a commercial A356 alloy. The predicted phase transitions were examined by DTA experiments and micrograph investigations using SEM/EDX/EBSD. The experimental results are in a good agreement with the calculated Scheil-solidification behavior.
