Abstract: | The texture evolution of ferritic hot rolled Ti-IF steel during cold rolling was investigated in which the re-duction was from 15% to 85%. It was found that α fibre texture was monotonously intensified with the increase in the cold rolling reduction, while γ fibre texture changed in a different way. When the cold rolling reduction was in the range of 15%- 35% or 45%- 75%, γ fibre texture was strengthened; however, when the cold rolling reduction was 35%- 45% or 75%- 85%, the intensity of γ fibre was reduced. The γ fibre displayed a maximum intensity for the reduction of 75%, and the highest average plastic strain ratio was simultaneously obtained owing to the favorable recrystallization texture. |
