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.

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

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.

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

Neutron diffraction study of the Cr84.7Re15.3 alloy

AIP Advances, 2021
Measurements of the temperature dependence of electrical resistance (R) and neutron powder diffraction (NPD) of a Cr84.7Re15.3 alloy is reported. The magnetism originates from the formation of a spin-density-wave (SDW) as a result of nesting between the ...
