Neutron diffraction studies of magnetostrictive Fe–Ga alloy ribbons [PDF]

, 2008
Melt-spun Fe–Ga ribbons were prepared and some ribbons were annealed at 1000 °C for 1 h then slowly cooled to room temperature. X-ray diffraction patterns revealed no evidence of texture and only bcc phase in the as-quenched ribbons.

Recent Progress of Residual Stress Distribution and Structural Evolution in Materials and Components by Neutron Diffraction Measurement at RSND

Quantum Beam Science, 2018
Neutron diffraction is an effective and nondestructive method to investigate inner structure and stress distribution inside bulk materials and components. Compared with X-ray diffraction, neutron diffraction allows a relatively high penetration depth and

Neutron strain scanning of fibre and diode laser welds in stainless steel and Ti6Al4V [PDF]

, 2014
Fibre lasers provide an unprecedented combination of high beam quality, brightness and low cost. Fibre laser beams can provide an exceptionally high power density beam with a relatively large depth of focus.

Single-Crystal Diffraction at ORNL: Historical Development, Current Advances, and Future Perspectives [PDF]

Structural Dynamics
Since the pioneering neutron diffraction experiments by Ernest O. Wollan and Clifford G. Shull in the 1940s, Oak Ridge National Laboratory (ORNL) has played a central role in the advancement of single-crystal diffraction techniques.

Strain mapping and nanocrystallite size determination by neutron diffraction in an aluminum alloy (AA5083) severely plastically deformed through equal channel angular pressing [PDF]

, 2013
Six specimens of an aluminum alloy (AA-5083) extruded by Equal Channel Angular Pressing following two different routes plus a blank sample were examined with a neutron radiation of 1.5448 Å. Macrostrain maps from the (311) reflection were obtained.

Investigation of Structural and Thermal Evolution in Novel Layered Perovskite NdSrMn2O5+δ via Neutron Powder Diffraction and Thermogravimetric Analysis

International Journal of Chemical Engineering, 2020
Neutron diffraction is one of the best methods for structural analysis of a complex, layered perovskite material with low symmetry by accurately detecting the oxygen positions through octahedral tilting.

Diffraction of Neutrons by Imperfect Gases [PDF]

Physical Review, 1958
The theory of cluster expansions is studied by a new method. A general procedure for obtaining the thermal average of a many-body function as a series in powers of density is derived. A recipe based on the Daker-Hausdorff theorem for reducing quantum thermal averages to their classical analogs is also described.

Load partitioning and evidence of deformation twinning in dual-phase fine-grained zr-2.5%Nb alloy. [PDF]

, 2013
In situ neutron diffraction loading experiments were carried out on a cold-rolled dual-phase (a-phase, '"' 10% b-phase) Zr–2.5%Nb alloy at room temperature. The specimens were cut at different angles from the rolling direction (RD) towards the transverse

Problems in using a comb sample as a stress-free reference for the determination of welding residual stress by diffraction [PDF]

, 2010
Precise measurement of a stress-free reference lattice parameter is vital in the determination of residual stress by diffraction techniques using θ/2θ-based analyses.
