Abstract
The dependence of static recrystallization characteristics on deformation and annealing conditions has been examined for vacuum melted and zone-refined iron deformed in torsion at high temperatures in the α range. The kinetics of recrystallization are strongly accelerated by increasing deformation at low strains, but are virtually independent of strain in the “steady-state” region of the high temperature flow curve. In the latter case the kinetics of recrystallization are greatly influenced by the dynamic restoration process operative during hot deformation. In particular, for the same material, static recrystallization is faster in dynamically recovered than in dynamically recrystallized structures due to a decrease in growth rate with tie in the latter. This and other differences in the static recrystallization behavior of these two structures are discussed in terms of the differences in their microstructural features.
