Effect of Intermediate Annealing on the Texture and Formability in Ferritic Stainless Steel Sheet

페라이트 스테인리스 강판의 집합조직과 성형성에 미치는 중간열처리의 영향

In order to improve the sheet formability of the ferritic stainless steel, the through-thickness textures of the recrystallized sample was modified by means of a thermomechanical treatment. An annealing process between the cold rolling reductions modified the preferred orientations throughout the thickness, which resulted in the modification of the final cold rolling texture as well as the final recrystallization texture. With the help of the modification of the recrystallization texture by the intermediate annealing, improvement of the sheet formability, i.e. an increase of the Lankford value.
