Possibilities of Fe-RICH phases elimination with using heat treatment in secondary Al-Si-Cu cast alloy

Possibilities of Fe-RICH phases elimination with using heat treatment in secondary Al-Si-Cu cast alloy

The mechanical properties of Al-Si-Cu cast alloy are strongly dependent upon the morphologies, type and distribution of the second phases. The skeleton like – Al<sub>15</sub>(FeMn) <sub>3</sub>Si<sub>2</sub> and needles - Al<sub>5</sub>FeSi phases were...
