The present study investigates the influence of manganese level and cooling rate on the formation of iron compounds and mechanical properties of Al-9%Si alloys containing 0.3%Fe. It has been established that high cooling rates and Mn additions are not able to totally nullify the formation of P-Al5FeSi-needles onto ot-Al 15 (Fe,Mn)3 Si2 -Chinese scripts even at Mn:Fe ratio of 2: 1, but produces improvement in tensile strength unlike the ductility which suffers a loss with the increment of Mn concentrations.
