Refinement of the Microstructure of an Al-Mg₂Si Hypereutectic Alloy by Intensive Melt Shearing

Article Preview

Abstract:

Attention has been given to the microstructural refinement by high shear processing of hypereutectic Al-Mg₂Si alloys as a potential in-situ composite for high-performance structural applications. The results demonstrate that intensive melt shearing promotes the formation of a refined compact polyhedral morphology of primary Mg₂Si and refines both the eutectic cell size and the lamellar spacing of Al-Mg₂Si pseudo eutectic structures. The refinement mechanisms are discussed.
