Abstract

In this studythe effectof SR and SB onsiliconmodificationwereinvestigated.Casting properties, Le. tendency to produce the porosity of both SR and SB treated alloys were evaluated. Finally, the effect of heat treatment on TENSILE and FATIGUE properties and silicon morphology was examined. Modification by SR can convert the silicon phase from acicular to fibrous. The optimum amount of SR content for achieving a modified fibrous structure in a sand mould is 0.013% SR (by weight), whereas the amount for SB is around 0.1%. Castings modified with SR develop a significant increase in porosity, whereas little effect was observed in alloys treated with SB. Mechanical properties of the modified A356 alloy were superior to the unmodifiedalloy. Solution heat treatment at 540°C for 6 hours, water quenching and aging at 150°Cfor 3 hours significantly enhance these properties
