摘要：

An AZ31 magnesium alloy was cast by the direct strip casting (DSC) process. Prior to casting, the melt was treated with a commercial Al-Ti-B refiner. By subsequently hot rolling the cast strip at 400 degrees C, a 1 mm thick sheet was produced. The microstructures of DSC and the hot rolled magnesium were examined by optical microscopy and the hardness was measured. The flow curves of the cast material were determined at 200 degrees C, 300 degrees C and 400 degrees C by compression tests with a deformation dilatometer and dynamic recrystallization was found to take place at 300 degrees C and 400 degrees C. The thermal stability of the hot rolled sheet was investigated by an isochronal annealing treatment over a wide range of temperatures between 100 degrees C and 460 degrees C. (C) 2010 Elsevier B.V.
