The experiment of ultrasonic cast-rolling magnesium strip was carried out on the horizontal twin-roll cast-rolling machine with the ultrasonic pole used in the solidification. The microstructures of ultrasonic and general cast-rolling magnesium strip were characterized. The results showed that the cellular dendrite of the general cast-rolling magnesium strip was coarse, the grain structure was heterogeneous and the average grain diameter was between 50μm~60μm. However, the grain structure became more homogenize after the ultrasonic treatment for cast-rolling magnesium strip, the grain was refined and the average grain diameter was between 20μm~30μm. Besides, the mechanical properties test results show that the tensile strength, yield strength and elongation of the ultrasonic cast-rolling magnesium strip were increased by 22.85%, 49.78% and 123.06% than those of the general cast-rolling magnesium strip.

Twin roll casting process combines casting and hot rolling into a single process. In this study, mechanical properties at room temperature and microstructure of the twin roll cast AZ91 magnesium alloy are investigated. The alloy exhibited a good combination of high ultimate strength of 343MPa, yield stress of 224MPa and elongation to failure of 13%. The mechanical property was very excellent compared with AZ91 die-cast alloy. EPMA analysis reveals that the Al concentration in Mg matrix is higher in twin roll cast alloy than that in die-cast alloy. This high Al concentration must be the origin of the good mechanical properties of twin roll cast alloy at room temperature.
