Investigation of titanium grade (Ti-Gr) polycrystalline samples by high-resolution three-axis neutron diffractometer

Original language description

New focusing 3-axis diffractometer set-up equipped with the bent-perfect-crystal (BPC) monochromator and analyzer with the sample situated in between which has offered the sensitivity in determination of strains Δd/d &lt; 10-4 in polycrystalline materials, has been introduced recently. The resolution determined by FWHM of the diffraction profiles is about one order of magnitude higher with respect to that of conventional 2-axis neutron strain/stress scanners. Therefore, the new set-up also offers the possibility of line profile analysis for relatively large irradiated gauge volumes and reasonable counting times, because the 3-axis set-up exploits focusing in real and momentum space simultaneously. The analysis is carried out by rocking the BPC analyzer, which provides the diffraction profile characterizing the sample. The neutron signal is registered by a point detector. In this case Titanium Grade 2 polycrystalline samples exposed to an external load by CONFORM-ECAP (C-E) and the Rotary Swaging (RS) were investigated. The influence of plastic deformation on the measured diffraction profiles is documented.
