“…The delta phase varies from 0 to 6.1 wt% and is much more pronounced in the mid-rib of the sword, with the exception of point 8 on the mid-rib (where the delta phase is missing), and on point 3 on the handle (where it has a strong presence). With respect to the blade of the sword, the tin contents on the edge (10,11,13,14) are observed slightly higher on the edge (12.5 wt%) compared to the centre of the mid-rib (11.9 wt%). This difference is not considered significant and might be due to the difficulties to fit the highly structured peaks measured in the mid-rib.…”

“…Fifteen analysis points were chosen (see Fig. 1b), inside the hilt (1-4), on the rivets (6, 7), inside the mid-rib of the blade (5,8,9,12,15), and on the edge of the blade (10,11,13,14). The collection time per point was about 30 min.…”

“…For effective alignment of the object a laser point cloud model, and from that a meshed model, of the outer dimensions of the sword was created using a robotic laser arm. The virtual laboratory software SScanSS [10] was used to select the analysis points inside the sword and to simulate the movements of the object on the instrument. Mounted on top of the moving system on ENGIN-X, the object was aligned by scanning several fiducial (marker) points on the aluminium frame with a laser touch probe.…”

Two neutron based techniques, neutron resonance capture analysis (NRCA) and time-of-flight neutrondiffraction (TOF-ND) have been used to determine the elemental composition and structure of a precious and very well preserved all-metal sword from the Bronze Age. This Buggenum sword was on loan from the National Museum of Antiquities (NMA) in Leiden (NL). NRCA and TOF-ND experiments have been carried out at a number of more or less identical positions of the sword. The tin-bronze ratio and the relative amounts of some minor elements (Sb, As, Ag, In) have been determined. The results of neutron diffraction measurements showed considerable tin-segregation, and clear indications of hardening on the edges of the blade. In addition, radiographs using Bremsstrahlung revealed the construction of the hilt-blade connection. The work was carried out at the EC Joint Research Centre IRMM in Geel (B) and at the ISIS facility of the Rutherford Appleton Laboratory (UK).

“…To optimize strain scanning experiments ENGIN-X is equipped with virtual laboratory software named The Strain Scanning Simulation Software (SScanSS) [19,20]. The SScanSS software, which was developed by the Materials Engineering group at the Open University in close collaboration with the ENGIN-X instrument scientists, utilizes Virtual Reality (VR) computer techniques to provide tools for planning, optimizing and executing experiments.…”

“…Effective procedures to maximize the usable neutron measurement time are vital. To optimize strain scanning experiments on ENGIN-X where, in particular, the samples have a complex geometry, the virtual laboratory software, SScanSS (Strain Scanning Simulation Software) [19,20] was developed.…”
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.
