Texture Development and Simulation of Inhomogeneous Deformation of FeCr during Hot Rolling

Optimizing continuous annealing of interstitial-free steels for improving deep drawability

“…Ferritic hot rolling usually leads to more pronounced hot band textures, particularly in the center layers. [34][35][36][37][38][39][40][41] The textures of the laboratory heat-treated samples of steels 1 and 3 (Figures 7 through 10) are similar to the The higher the hot rolling temperature is, the higher the in-plane hot band texture homogeneity usually is. Ferritic hot behavior is not simply a static characteristic that pertains to a certain orientation, but a history-dependent quantity rolling, as encountered in certain low carbon steel processing lines or in highly Cr-alloyed ferritic stainless steels, usually depending on both orientation and orientation path.…”

“…It was shown in previous works that the crystallographic texture is usually In most cases, variations in the annealing treatment do not affect the recrystallization texture markedly (Figures 7 a more sensitive indicator for hot-band homogeneity than the grain microstructure. [34][35][36][37][38][39][40][41] Hot-band texture serves as a and 8). This is not true for steel 3, where annealing cycle 6 entails a significantly sharper ␥-fiber when compared to starting texture for cold rolling and subsequent recrystallization.…”

“…Increase in hot-band, texture sharpness occurs with increas- regime during hot rolling. [34][35][36][37][38][39][40][41] Commercial hot rolling conditions always lead to a strong through-thickness gradient in the displacement field creating a pronounced profile of shear and strain energy. While deformation in the center layer is closer to a plane strain state, layers closer to the surface undergo strong shear deformation and accumulate more deformation energy.…”

On the inhomogeneity of the crystallographic rolling texture of polycrystalline Fe3Al

“…From measurements on ferritic stainless steels, it is well established [35][36][37] that in these layers the most relevant rolling texture components are located. Stipulating a certain resemblance between bcc and imperfectly B2 ordered alloys, the texture measurements were hence conducted in two different through-thickness layers.…”

“…Relevant texture components, which are typically generated during rolling of B2 ordered iron aluminides [26][27][28][29][30] and non-ordered bcc alloys, [31][32][33][34][35][36][37] are usually arranged along certain fibers through Euler space. It is hence convenient to describe the orientation distributions observed in terms of texture fibers, which can either be presented employing iso-intensity diagrams (w 1 sections) or so-called fiber diagrams (Fig.…”
