Abstract

The influence of large (> 1 μ m diameter) particles on the recrystallization behaviour of magnesium alloys deformed in 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. © 2009 Acta Materialia Inc.
