Although the cascade of material flow is suitable for the aluminum recycling due to without or less dilution by raw material, better utilization of secondary alloys will be desired. To control formability in aluminum cast materials, fine microstructure with plural phases is one of candidates for the material design. A novel thermomechanical process, repeated thermomechanical treatment (RTMT) has been applied to hyper-eutectic Al-Si-X hot-worked materials. Through the hot-working and RTMT, the casts could be plastically deformed, and substantially refined microstructures with balanced strength and ductility have been successfully obtained.
