摘要：

The influence of large (> 1 mu m diameter) particles oil the recrystallization behaviour of magnesium alloys deformed ill plane strain compression has been studied. Deformation zones characterized by a misorientation gradient were observed surrounding large particles. which were similar to those seen in other alloys where particle-stimulated nucleation (PSN) of recrystallization occurs. During annealing, new grains formed by PSN, but only at a small fraction of the coarse particles. Recrystallization was instead dominated by growth of existing dynamically recrystallized grains and nucleation of new grains from the deformed grain mantle region. (C) 2009 Acta Materialia Inc.
