Influence of multiple small-angle neutron scattering on diffraction peak broadening in ferritic steel

Peak broadening of neutron diffraction was studied at various neutron to the beam direction. Small-angle neutron scattering results showed significant reduction broadening can be attributed to multiple sma...

The Study of x-T Phase Diagram of Rb1-x(NH4)xI Mixed Crystals by Neutron Diffraction

The crystal structure of the mixed crystals and amonium dynamics were studied by the powder neutron diffraction and by the inelastic incoherent neutron scattering methods. The x-T phase diagrams were determined. Re...

Interplay between local structure and nuclear dynamics in tungstic acid: a neutron scattering study

We provide an exhaustive characterization of structural properties and nuclear dynamics in tungstic acid (WO3·H2O). To this end, we employ neutron and X-ray diffraction (ND and XRD) combined with inelastic neutron scatt...

Magnifying effect by neutron diffraction on cylindrically bent perfect crystal (BPC) of Si in fully asymmetric diffraction geometry

Low absorption of neutrons in Si crystal enables using the fully asymmetric diffraction geometry (FAD) of the single crystal slab in which neutron beam can pass deformation a neutron beam can meet, on the path, the...

Use of small angle neutron scattering and X-ray powder diffraction with the Rietveld method in the assessment of firing conditions in historical fired-clay bricks

In this work, the potential of small angle neutron scattering (SANS) and X-ray powder diffraction (XRPD) with the Rietveld method (including the quantification of the amorphous fraction), is evaluated in the investigation o...
