Abstract

Strips of AZ31 were produced by Direct Strip Casting and subsequent hot rolling at 400°C. The texture and microstructure of the strips in as cast and hot rolled condition were investigated. The cast strip exhibited a random distribution of the grain orientations while a strong basal-type texture was observed in the hot rolled sheets. The flow curves of the Direct Strip Cast material were obtained by hot compression experiments and dynamic recrystallization was found to occur at all studied temperatures and strain rates. The tensile properties of strip cast and hot rolled magnesium were examined by tests at room temperature. Grain refinement and the development of the basal texture during hot rolling resulted in high strength of the hot rolled magnesium sheet.
