When a ferrite steel is subjected to extremely heavy drawing, microstructure becomes nano-sized. Here, changes in microstructure and texture by annealing was investigated in order to estimate the restoration process of a heavily drawn ferrite steel by using neutron diffraction and EBSP. Drawn ferrite steel shows the <110>fiber texture along the drawing direction. The intensity of pole density decreased by annealing in weakly deformed specimen, while it did not change in case of heavily deformed one. This result sujests the restoration progress due to only grain growth in the heavily deformed ferrite steel.
