Mechanical Deformation and Heat Treatment Processing of Twin Roll Cast and Melt Processed Al-5 wt.% Mg Alloy Strips

Abstract Twin-roll casting (TRC) is a set up applied to manufacture sheets of aluminium alloys. In spite of huge potential, extreme centerline segregation emerges during casting. This segregation limits the range of alloys suitable for commercial applications. To enhance the quality of the TRC strips, another innovation– the melt-conditioning twin-roll casting (MCTRC) – has been used. Cold rolling followed by homogenization heat treatment of the MCTRC strip results in more uniform solute distribution across the thickness of the strip, leading to strips of higher quality as compared to the conventional TRC strip.
