Development of High-Strength Aluminum Alloys Using Rapid Solidification Processes

Attributed primarily to its excellent high-strength to weight ratio and corrosion resistance, high-strength aluminum alloys are widely used in automotive industry. The sheet products of high-strength age-hardenable alloys are already adapted for inner and outer panels in airplanes and high-tech automobiles. However, the sheet production of age-hardenable Al alloys by conventional direct casting is far more expensive as compared to twin roll casted sheet products of aluminum. Reduction of the production costs and energy saving can be achieved by a continuous casting process like twin belt casting (TBC) and twin-roll casting (TRC) process. The major problem in adapting the conventional high-strength aluminum alloys is their wide solidification range (~100 °C) which results in serious segregation problem upon rapid solidification. Adaptation of twin roll casting to high strength age-hardenable Al alloys would be a great breakthrough in sheet metal production. The major part of the efforts in the literature was extended to conventional Al alloys such as AA5754, AA5182, AA2024 and AA7075. These traditional efforts have not resulted in any successful outcomes till now which indicates the necessity of following innovative and brand new approaches. In this respect the aim to project is to create new high strength Al alloys for rapid solidification processes.
