Torsion testing was carried out on a plain carbon steel to
study ferrite grain refinement during warm deformation within two-phase (alpha+gamma) region.
Fine ferrite grains development was analyzed by using optical microscope and EBSD technique.
Microstructural analysis shows that with increasing strain the new fine equiaxed ferrite grains
surrounded by high angle boundaries start generating at the initial boundaries and the volume
fraction of fine grains is increased and that of work hardened grains decreased. It was seen that
there is no evidence of discontinuous dynamic recrystallization. Thus, it is suggested that the
occurrence of continuous dynamic recrystallization is responsible for the formation of new fine
ferrite grains. (c) 2007 Elsevier B.V. All rights reserved.
