For the effective phase imaging at pulsed neutron sources, we have designed and developed the multi-colored Talbot-Lau interferometer which works at several wavelengths. At the Energy Resolved Neutron Imaging System RADEN in J-PARC, we demonstrated its operation by observing the visibilities of moire fringes derived from different wavelengths (0.25, 0.50, and 0.75 nm). We also investigated the variation of moire fringes dependent on the wavelength resolution from 18% to 50% and showed the advantage of pulsed beams. At the central wavelength of 0.5 nm, we have succeeded in interferometric imaging for the samples of metal rods made of aluminum, lead, and copper. An absorption grating as an analyzer was fabricated by imprinting of metallic glass for the first time, and showed a clear moire fringe with the high visibility of 68% and a well-controlled shape in comparison with previous ones fabricated by oblique evaporation of gadolinium.

Evaluation of compressive deformation behavior of Zr$$_{55}$$Al$$_{10}$$Ni$$_{5}$$Cu$$_{30}$$ bulk metallic glass containing ZrC particles by synchrotron X-ray diffraction

Compressive deformation mechanism of a Zr$$_{55}$$Al$$_{10}$$Ni$$_{5}$$Cu$$_{30}$$ bulk metallic glass containing 10vol.%ZrC (ZrC-BMG) was evaluated by measuring the residual strains in the compressive deformed samples using the synchrotron X-ray diffraction and also evaluating the localized deformation behavior around the ZrC particles by the finite element analysis. Phase stress shared by the metallic glass matrix was increased before macroscopic yielding due to local plastic deformation around the ZrC particles. After macroscopic yielding, the phase stress shared by the ZrC phase was drastically increased, and finally the ZrC-BMG was fractured by breaking the ZrC particles reaching its fracture strength.

Evaluation of deformation behavior on ZrC particle reinforced Zr-Al-Ni-Cu metallic glass using neutron diffraction technique

Suzuki, Hiroshi; Imafuku, Muneyuki*; Saida, Junji*; Setyawan, A. D.*; Kato, Hidemi*

no journal, , 

Deformation behavior on a Zr$$_{55}$$Al$$_{10}$$Ni$$_{5}$$Cu$$_{30}$$ bulk metallic glass containing 10 vol%ZrC particles were measured using neutron diffraction. Elastic deformation behavior under uniaxial tensile loading can be predicted by the Self-Consistent model. Higher strength in compressive deformation in this sample is originated from the thermal tensile residual stresses, and from the phase stresses transferred to the metallic glass matrix which are 5% less than the applied stresses under uniaxial loading.

The plutonium and uranium nitrate solution processes evaporation, the concentrate, and the denitration with the micro wave denitration apparatus. It is necessary to grasp the electric field in the denitration apparatus to irradiate the micro wave efficiently. It reports on the result of behavior of the electric fieldin the denitration apparatus by the electric field analysis.
