Dynamic recrystallization during hot deformation of an armco steel
Keywords:Dynamic recrystallization, Avrami equation, ARMCO steel, Hot working,
The onset and kinetics of dynamic recrystallization of an ARMCO steel is characterised in this wok. For this purpose, uniaxial hot compression tests were carried out. The Avrami equation was employed to describe the kinetics of recrystallization. Moreover the critical strain determining the onset for dynamic recrystallization was analysed. It was observed that the latter characteristic parameters were strain rate and temperature dependent. A comparison with published results and a derivation of the possible effect of chemical composition is also offered.
