Effect of rolling temperature on the recrystallization texture of warm rolled steels
Warm (ferritic) rolling trials were carried out on a Nb-stabilized interstitial-free (IF) steel, an extra low carbon (ELC) steel and an experimental low carbon-chromium (LC(Cr)) material at temperatures between 440 and 710degreesC. The influence of rolling temperature on the recrystallization textures was investigated, together with the effects of coiling simulation. The texture intensities of the IF steel were relatively unaffected by rolling temperature; conversely those of the ELC material were strongly temperature dependent. The addition of chromium was found to aid development of the shear bands at the higher rolling temperatures and hence strengthen the (111) component and the product formability. Coiling simulation further intensified the recrystallization textures of the Nb-IF and LC(Cr) steels. These effects are attributed to the intensity and frequency of shear band formation and the dynamic strain aging behaviors of the various materials.
