Comparison between recrystallization mechanisms in copper and Ti-IF steel after a low amount of deformation

A comparison is proposed between results published recently on recrystallization of bcc (body-centered cubic) alloys such as Ti-IF steel and on face-centered cubic (fcc) material such as copper. The stored energy during the deformation by both crystallographic structures and the evolution of the microstructure during recrystallization (recovery, coalescence, subgrain growth and grain growth…) are detailed. The similarity of mechanisms involved during the recrystallization is discussed.

Research highlights
► Copper and IF steel sub-structure after low deformation depending on crystallographic orientation.
► Recovery mechanisms by cell coalescence and dislocation rearrangement.
► A comparison of recrystallization mechanisms in bcc and fcc alloys.
► The similarity of recrystallization mechanisms is observed between bcc and fcc alloys.
► Texture components of low energy and of cellular sub-structure have an advantage for recrystallization.
