Accuracy of Measuring Rebar Strain in Concrete Using a Diffractometer for Residual Stress Analysis

Quantum Beam Science, 2023
Neutron diffraction is a noncontact method that can measure the rebar strain inside concrete. In this method, rebar strain and stress are calculated using the diffraction profile of neutrons irradiated during a specific time period.

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 ...
