Abstract
The recrystallization of pure iron deformed at 250°C by shear under pressure has been studied by scanning electron microscopy and durometry. The completeness of dynamic recrystallization has an effect on further static recrystallization: in a structure of a mixed type (formed by dislocation cells and individual recrystallized grains), the appreciable growth of a grain is started at a temperature that is 100°C lower than in a submicrocrystalline (SMC) structure (composed of grains formed as a result of dynamic recrystallization). An inhomogeneous character of the structure created under dynamic recrystallization conditions causes its low thermal stability. For the SMC structure, its propensity to secondary recrystallization has been revealed.
