摘要：

Grain refinement during forging was found to be due to dynamic recrystallization of four kinds of Mg-x wt.%Al-1 wt.%Zn (x = 3,4,5,6) alloys with grain sizes of similar to 30 mu m, which were cast using a thixo-molding machine. Superplastic forming combined with forging was successfully performed at a low temperature (473 K) and high-strain rate (3.3 x 10(-2) s(-1)). (c) 2006 Acta Materialia Inc. Published by Elsevier Ltd.
