Abstract

The recrystallization textures and drawability in an interstitial-free (IF) steel were investigated as a function of cold rolling reduction. The hot bands for further cold rolling were obtained by lubricated hot rolling in the ferrite region. The orientation distribution function (ODF) was applied to analyze recrystallization textures. Texture analysis showed that hot bands rolled in the ferrite region had strong {111}//ND texture component. The {111}//ND recrystallization texture of the cold rolled steel with 73% reduction displayed the highest intensity, but weakened as more cold work was introduced. The highest r-value was obtained at a cold reduction of 73% when the hot band was previously rolled in the ferrite region.
