“…In this study, an ENGIN‐X diffractometer was used (Zhang et al . , 78), which is optimized for measurements of residual stresses in different defined parts inside an object (‘gauge volume’). Diffraction measurements on the ENGIN‐X were made with gauge volumes of 4 × 4 × 10 mm 3 along the length of the objects in their central part, and also on the blades.…”

Thirteen bronze battleaxes from Middle Bronze Age II graves at Rishon LeZion, Israel were analysed by ED XRF at multiple surface locations in order to determine their metallurgical composition. Six of these were further subjected to neutron diffraction using an ENGIN-X diffractometer in order to determine bulk phase composition. The results indicate that the previously established geographical and chronological variability in Sn-Cu (with occasional Pb) and As-Cu alloys found using the former method may be an artefact of preservation and conservation. In addition, the varying homogeneity determined by the latter reflects special treatment for improving on the metal cast.

“…There are several ways of measuring residual stresses in small volumes. The most common ones involve mechanical invasive methods (e.g., hole drilling or cutting [2,3]) and non-destructive methods using radiation such as x-ray (laboratory or synchrotron) or neutron diffraction [4][5][6][7][8]. Neutron diffraction is outstanding in the ability to obtain residual stresses non-destructively within the subsurface and deep within the bulk of the components.…”

The ENGIN-X beamline is mainly used to determine residual strains/stresses deep within the interior of bulk engineering components. It is mainly used by scientists and engineers for the development of modern engineering processes and structural integrity investigations. ENGIN-X diffraction and transmission mode can be a very useful tool to measure strain, phase transitions, texture and material composition in spatial resolution in historical or archaeological artifacts and modern materials. The complexity of the shapes and sizes of the samples measured on ENGIN-X varies significantly between experiments, and this required the development of better planning, simulation and control software, SScanSS. In this paper an overview of recent developments in strain scanning on ENGIN-X and a highlight of current scientific research are presented.

“…The average lattice spacing is measured in a specific direction within a scattering gauge volume defined by collimating or focusing the incident and scattered beams. Typical spatial resolutions for diffraction based techniques are of the order ≈1 mm for neutron or ≈1 µm for X-ray synchrotron experiments [7][8][9]. The elastic strain, ε, is defined as the relative shift in lattice spacing from the 'strain-free' value.…”

Using recently developed microchannel plate (MCP) neutron area detectors at a pulsed neutron source provides a method of fast non-destructive imaging and characterisation of advanced materials at unprecedented spatial resolution. The energy resolved neutron transmission spectrum can be found from the neutron time of flight (ToF), this provides valuable information about the crystallographic structure within the sample such as the average residual elastic strain in the incident beam direction. By measuring this spectrum at a number of sample orientations information is built up about the strain distribution throughout the specimen. The energy-resolved neutron transmission spectrum of an additively manufactured turbine blade was measured at the Engin-X instrument, ISIS, UK. A high resolution three-dimensional reconstruction of the neutron attenuation coefficient of the blade was recovered, then analysis of the energy resolved spectrum gave insight into the underlying residual elastic strain profile imparted by the advanced manufacturing process.
