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

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