Comparison of hot rolled textures in different grades of high formable steels

During hot rolling of steels phase transformation takes place. Hot band texture and hot band grain size largely influence the texture formation of cold rolled and annealed steels. Generally, a strong crystallographic relationship exists between the parent austenite phase and the product ferrite phase. The present investigation incorporates a comparative study of hot band texture formation in austenitic zone in extra deep drawing (EDD), interstitial free (IF) and interstitial free- high strength (IF-HS) steels. The intensities of hot band texture in IF-HS steel [f(g) = 19.6] were found to be much stronger in comparison to EDD [f(g) = 3.9] and IF [f(g) = 1.4] steels.
