Low vs. High stored Energy Recrystallization Textures in Interstitial Free Steel, presented by Leo A.I. Kestens, Ghent University
It is well known that the crystallographic texture is of paramount importance for the anisotropy control of a wide variety of material properties. E.g., for Non-Oriented grades of electrical steel the θ-fiber texture (<001>//ND) provides the best prospect for optimizing the magnetic properties. However, after conventional cold rolling and annealing of (ultra-) low carbon steels the γ-fiber texture (<111>//ND) appears, which is precisely opposite of what is necessary for the magnetic properties. One alternative to conventional cold rolling is warm rolling, i.e., rolling at elevated temperature but below the Ac1 temperature. It is well-known that recrystallization after warm rolling enhances the θ-fiber texture. However, the structural origin of this drastic texture change as a function of rolling temperature is not well understood. In this talk the recovered structure just before the onset of primary recrystallization is analyzed in detail on an interstitial free steel, which can be regarded as a model material for all ultra-low-carbon steels. A remarkable and statistically relevant difference is observed between the dynamically recovered structure after warm rolling to a reduction of 80% at 550°C and after static recovery at 500°C of a cold rolled sheet rolled to a reduction of 75%. It will be explained how subtle substructural differences are of crucial importance for texture formation during primary recrystallization.
