In this work, the influences of Fe, Mn and Y with various contents on microstructural evolution and mechanical properties of hypoeutectic Al–7%Si alloy were investigated by microscopy technology and tensile test. The results showed that the complex addition of Al–20%Si-2.5%Fe–2%Mn master alloy and r...
