Abstract

We investigated the feasibility of producing high strength Al alloy sheets with high solute contents using a twin roll strip caster equipped with an asymmetric nozzle. The combination of twin roll casting and the asymmetric nozzle used in this study reduced centreline segregation and hot tear, thereby increasing the casting speed. These features of the strip casting allowed the dissolution of more solute elements, suggesting the potential development of high strength Al alloys with a range of Mg contents up to 10 wt-%. The workability and mechanical properties of the cast strips were also evaluated to assess the feasibility of producing high strength Al alloy sheets superior to the present limit of conventional techniques.
