Paper Title:
Facilitated Recrystalization of the Hard-to-Recrystalize Structure in 16% Cr Steel Sheets by one-Pass ECAP Prior to Cold Rolling
  Abstract

The extended band structures of cold-rolled high Cr steel sheets are recrystallization resistant, and tend to become the so-called grain colony as a recovered state. It is shown that a novel approach involving strain-path change by introducing one-pass ECAP prior to cold rolling facilitated recrystallization. Indeed, recrystallization temperature was reduced by 100 °C, compared with cold rolling alone imposing the same equivalent strain. Dense deformation bands introduced during ECAP perturbed the banded structures and enhanced the recrystallization at final annealing.
