“…The hot rolling and cold rolling textures of ferritic stainless steels are very inhomogeneous through the thickness. [35][36][37] In this study all the textures were measured at the center layer with the strongest fiber texture. 37) Moreover, EBSP measurements were performed using Orientation Imaging MicrographTM (OIM) software equipped in a field emission type Scanning Electron Microscope (accelerated voltage 25 kV, beam step 2 mm).…”

“…It is found that recrystallization in a cold-worked low carbon steel is mainly controlled by the oriented nucleation theory/grain frequency effect that is governed by the orientational dependence of the stored deformation energy (Hölscher et al, 1991.) The two key recrystallization texture components in steel are {110}<1 1 0> and {554}<22 5 >.…”

“…11,[25][26][27] In this paper, the {334}͗483͘ and {112}͗110͘ components were calculated to obey an approximate 26°͗110͘ orientation relationship, close to the orientation relationship of coincidence site lattice (CSL)S19a (27°͗110͘) grain boundaries, which display high mobility. 28) Therefore, {334}͗483͘ recrystallization texture could have been developed from the scattered cold rolling textures by a 26°͗110͘ selective grain growth in the vicinity of the pre-existed high-mobility CSL-grain boundaries.…”

In order to optimize the formability of ferritic stainless steel (FSS), control of the crystallographic texture is essential. In the present work, texture development of cast strips with different initial solidification structure during rolling and subsequent annealing and the formability of final sheets were investigated. Fully equiaxed and columnar grained cast strips of Fe17%Cr FSS were fabricated by a pilot twin-roll strip caster. The equi-axed and columnar grained bars cut from a conventional continuous cast slab were used as comparable specimens. It was shown that in the cold rolled and annealed sheet of fully equi-axed cast strip, uniform and strong g-fiber recrystallization texture was formed and {001}͗110͘ component was almost eliminated. By contrast, the recrystallization texture in the conventional sheets with equi-axed and columnar initial solidification structures exhibited typical shift towards high-index {334}͗483͘, which led to a reduced r-value as compared to that of the equi-axed cast strip. The final annealed sheet of fully columnar cast strip, however, showed weaker g-fiber recrystallization texture and lower r-value than those of conventional sheets. It is, therefore, believed that twin-roll strip casting can improve the formability of 17 % Cr FSS only under the precondition that appropriate solidification structure is obtained.KEY WORDS: ferritic stainless steel; twin-roll strip casting; solidification structure; texture; formability. ent strips in cold rolling and annealing were studied. Equiaxed and columnar bars were cut from a continuous cast slab, and hot rolling, hot band annealing, cold rolling and final recrystallization annealing were performed for both bars to simulate the industrial processes. The texture developments of the two bars were also studied and compared with those of cast strips to understand the evolutions of microstructure, texture and properties in the cast strips. Experimental ProceduresFe17%Cr FSS with a composition of Cr, 16.9; Ni, 0.114; C, 0.03; Mn, 0.154; Si, 0.243; P, 0.016; S, 0.004 (in mass%) was used. Cast strips were produced by using a pilot twinroll strip caster, in which the molten steel was poured into a preheated tundish under Ar shield to flow through a nozzle into the rotated water-cooled rolls.15) The casting speed was set up to be 0.25 m/s and the initial roll gap was set to be 1.5 mm to produce strips with thickness of about 1.8 mm. The pool melt temperature was measured by a thermo-detector installed above the melting pool. In the present work, pool melt superheats were controlled to be about 140 K and 20 K, respectively, to produce fully columnar and fully equi-axed cast strips, Fig. 1. The average diameters of columnar and equi-axed grains were about 400 mm and 200 mm, respectively. Both strips were cold rolled by using a laboratory rolling mill with a thickness reduction of 80 %, and were annealed at 860°C for 2 min.Columnar and equi-axed bars in the size of 250 Lϫ 110 Wϫ45 T (mm) were cut from a cast slab of Cr17 FSS, Fig. 2.

Rolling and recrystallization textures of bcc steels

Abstract: The rolling and recrystallization texture development of bcc steels is discussed for three examples belonging to three different types of steels, namely deep drawing steels (e.g. low carbon steel), ferritic stainless steels (e.g. Fe16%Cr) and electrical steels (e.g. Fe3%Si).
