摘要：

The application of hot extrusion and high-speederatio differential speed rolling (HRDSR) to a Cacontaining Mg3A14Zn magnesium alloy, processed by electromagnetic casting in the presence of electromagnetic stirring, produced a novel microstructure, composed of an ultrafine grain size of less than 1 im and very fine (Al,Mg)2 Qa particles that were uniformly and densely distributed over the matrix. The HRDSR processed alloy exhibited excellent superplasticity at relatively low temperatures (below 23 K). © 2009 WILEY-VCH Verlag GmbH & Co, KGaA.
