Abstract
In this study, hypo-eutectic aluminum -silicon (Al-Si) alloy has been developed through modified strain-induced melt activation (modified SIMA) process. Microstructural features of modified SIMA processed Al-7Si alloy is fine, globular α-Al grain and uniformly distributed fragmented eutectic silicon. The developed alloy shows remarkable ultimate tensile strength (UTS, 204 MPa) with exceptionally achieved ductility (El, 30%). Globular morphology of α-Al grain and fine fibrous, uniformly distributed eutectic silicon maintain a proper balance in the strength and ductility of modified SIMA processed Al-7Si alloy .
