“…In other words, <110> faces to the neutron incident/transmission direction, namely, the preferred orientation parallel to the beam direction at the RD rolled area is <110>. This is consistent with the well-known preferred orientation of rolling textures [34]. On the other hand, at the ND rolled area, {110} Bragg-edge transmission intensity has a valley near λ = 0.35 nm (θ 110 = 60 • ).…”

“…This means the crystallite size becomes smaller at welded zones (the extinction effect becomes small). It was well known that the preferred orientation parallel to the rolling direction of α-iron plate is <110> and the preferred orientation perpendicular to the rolling direction of α-iron plate is <111> [34]. In this experiment, it was investigated whether the Bragg-edge transmission imaging with the RITS code can identify the correct preferred orientation.…”

Current status of Bragg-edge/dip neutron transmission analysis/imaging methods is presented. The method can visualize real-space distributions of bulk crystallographic information in a crystalline material over a large area (~10 cm) with high spatial resolution (~100 µm). Furthermore, by using suitable spectrum analysis methods for wavelength-dependent neutron transmission data, quantitative visualization of the crystallographic information can be achieved. For example, crystallographic texture imaging, crystallite size imaging and crystalline phase imaging with texture/extinction corrections are carried out by the Rietveld-type (wide wavelength bandwidth) profile fitting analysis code, RITS (Rietveld Imaging of Transmission Spectra). By using the single Bragg-edge analysis mode of RITS, evaluations of crystal lattice plane spacing (d-spacing) relating to macro-strain and d-spacing distribution's FWHM (full width at half maximum) relating to micro-strain can be achieved. Macro-strain tomography is performed by a new conceptual CT (computed tomography) image reconstruction algorithm, the tensor CT method. Crystalline grains and their orientations are visualized by a fast determination method of grain orientation for Bragg-dip neutron transmission spectrum. In this paper, these imaging examples with the spectrum analysis methods and the reliabilities evaluated by optical/electron microscope and X-ray/neutron diffraction, are presented. In addition, the status at compact accelerator driven pulsed neutron sources is also presented.

“…It is stable and its intensity increases with deformation. 28,29) In order to investigate an initial stage of recrystallization, annealing was carried out at 695°C (Ϯ5°C), which is lower compared with the conventional annealing temperatures. Figures 6 and 7 show the hardness and microstructures of the 80 % cold-rolled specimens as a function of time at 695°C, respectively.…”

The evolution of recrystallization textures in cold-rolled Ti bearing interstitial free (IF) steel sheets were investigated using X-ray pole figures and electron back scattering diffraction (EBSD). A hot band of IF steel was cold-rolled by 50, 80, and 95 %. The deformation texture of cold-rolled steel sheets consisted approximately of the ͗110͘//RD (a fiber) and the ͗111͘//ND (g fiber) with high densities in the {001}͗110͘, {558}͗110͘, and {665}͗110͘ orientations. When annealed at 695°C, the cold rolled sheets developed a recrystallization texture characterized approximately by the g fiber whose main components were approximated by {111}͗112͘, {334}͗483͘, and {665}͗1 1 2.4͘ which is almost the same as {554}͗225͘. The densities of these orientations increased with increasing cold-rolling reduction. The recrystallized {111}͗112͘, {334}͗483͘, and {665}͗1 1 2.4͘ grains were attributed to the {001}͗110͘, {558}͗110͘, and {665}͗110͘ deformation orientations by the strain energy release maximization (SERM) model for recrystallization texture, in which the absolute maximum internal stress direction in the deformed state tends to be parallel to the minimum Young's modulus direction of recrystallized grains.
