摘要：
This paper reports a novel strategy to produce an ultra-fine grained (UFG) structure in an Al-4Mg (weight percent, wt%) alloy via discontinuous dynamic recrystallization under moderate straining (true strain <2.5) as imposed during conventional extrusion at 400 degrees C. The mechanisms underlying the occurrence of discontinuous dynamic recrystallization and the formation of the UFG structure were analyzed and discussed in detail. The UFG Al-4 wt%Mg alloy exhibits both high tensile yield strength and elongation. (c) 2013 Elsevier B.V. All rights reserved.
