Popis:	Techniques for controlling the texture of polycrystal materials are very important, because texture anisotropy has a strong effect not only on the characteristics of a steel sheet but also on the mechanical and electrical properties. We have produced fine-grained hot steel strips industrially through high-reduction low-temperature rolling and these steels have the same texture as that of thermomechanically rolled steels. In this study, we first obtained the critical resolved shear stress of hot materials from functions of dislocation density and predicted the hot rolling texture in the nonrecrystallized austenite region using Taylor theory. Next, we predicted the transformation texture of fine-grained hot strips from the hot rolling texture of austenite in accordance with the Kurdjumov-Sachs orientation relationship. The accuracy of the new macro-micro combined model for texture evolution is excellent.
