Relationship between rolling textures and shear textures in f.c.c. and b.c.c. metals

Texture investigation of the superelastic Ti–24Nb–4Zr–8Sn alloy

“…6b), the texture concentrates mainly on the γ-fiber, that is all the grains are oriented so that a {111} plane is parallel to the surface of the sample. This γ-fiber is commonly observed in bcc alloys [15][16][17] and was recently observed in β-titanium alloys after high deformation reduction rates [11]. At high cold rolling rate (CR94%-ST, Fig.…”

Evolution of microstructure in stainless martensitic steel for seamless tubing

“…However, in general, the spectrum of martensitic orientations remains the same. According to [8], the spectrum in these areas corresponds to α-phase orientations, resulting from two phase-shear transformations of strained stable-orientation austenite [9,10] in accordance with the orientation ratios between Kurdyumov-Sachs and Nishiyama-Wassermann. The distributions of the intercrystalline and special boundaries (Fig.…”

“…3, c, d). All the indicated orientations of the ferrite formed at HD, namely, {001} <110>, {11k} <110>, are stable deformation orientations of the BCC lattice [9]. It should be noted that, taking into account the crystal-geometric characteristics of δ-ferrite (orientation, shape and size of grains), it can be considered as a kind of "macrodefect", which needs to be eliminated by heat treatment.…”

Grain Refinement of C–Mn Steel to 1 μm by Rapid Cooling and Short Interval Multi-pass Hot Rolling in Stable Austenite Region

“…The former is typical of the cold-rolling texture of fcc metal with medium S.F.E., 33) and the latter is known as the surface shear texture that develops in surface layers of fcc materials when they are subjected to heavy shear deformation during rolling. 36,37) Therefore, the textures clearly indicate that the model alloy has undergone heavy deformation without intense recrystallization, and a large influence of shear stresses due to the friction between roll and sample surfaces on the deformation is manifest in the surface region. For comparison, the texture of the same alloy that has been air cooled after a similar hot rolling to promote recrystallization is shown in Figs.…”
