DOI: 10.1063/5.0085896
Abstract: Point by point strain scanning is often used to map the residual stress (strain) in engineering materials and components. However, the gauge volume and, hence, spatial resolution are limited by the beam defining apertures and… read more here.

DOI: 10.1103/physrevmaterials.1.053802
Abstract: Technological developments in high resolution time-of-flight neutron detectors have raised the prospect of tomographic reconstruction of elastic strain fields from Bragg-edge strain images. This approach holds the potential to provide a unique window into the… read more here.
