The Texture Evolution of Dual Phase Steel Sheets

Abstract

in this paper, the texture evolution of cold rolling and recrystallization of dual phase steel sheets is studied. The experimental results show that the cold rolling texture components are γ fiber (<111>//N.D.) and α fiber (<110>//R.D.). After heat treatment (austenizing temperatures 960°C and 980°C, 0.7°C/S cooling to 650°C, a rational holding time to form ferrite and martensite microstructure), the texture components are still γ fiber and α fiber, the recrystallization texture in dual phase steel sheet is remarkable different compared to the recrystallization texture in the pure (single phase) ferrite.
