Abstract

From the viewpoint of deep drawability, the influence of chemical compositions on the texture formation of steel sheets hot rolled below the Ar3 temperature (warm rolling) has been investigated using steels consisting of various combinations of carbon and titanium contents. Microscopic studies using transmission electron microscopy and selected area electron diffraction showed that in the presence of carbon in solution, {114} 110 direction - {112} 110 direction orientations were formed in the vicinity of grain boundaries by a unique crystal rotation different from that occurring in the matrix. The occurrence of the rotation is explained by the variation of active slip systems caused by work hardening due to the interaction between dislocations and interstitial atoms. The influence of grain size before warm rolling and recrystallization temperature on the texture formation, both of which were affected by chemical composition is also discussed.
