Solidification of aluminum copper alloy during twin roll strip casting

Abstract

Twin roll casting is an innovative route to produce thin metal strip directly from the melt. The paper, presents solidification characteristics of twin roll cast, Al-Cu eutectic alloys. Molten alloy was poured in the gap between the copper rollers to produce the strips. The rotational speed of the rolls could be varied from 10 rpm to 100 rpm. During this process, the melt solidified to form strip. A specimen of 50mm length cut from the cast strips was subjected to physical and mechanical characterization. Variation in hardness and microstructure of the produced trip is explained as a comparison to normal casting. � (2014) Trans Tech Publications, Switzerland.
