Abstract :Al-Si alloys with compositions 8, 12, 16wt% Si were manufactured by chill casting and melt-spinning insert ignore into journalissuearticles values(MS); methods. The resulting ribbon samples have been characterized by optical and scanning electron microscopy insert ignore into journalissuearticles values(SEM); and X-ray diffractometry and compared with their ingot counterparts. Microstructural examinations revealed that microstructures of the melt-spun ribbons were quite fine compared to their ingot counterparts. Both XRD analyses and microstructural examinations indicated that the solubility of Si in a -Al phase was nearly complete.
