“…This technique has been used to study lattice strains ; strain tomography (Hendriks et al, 2019(Hendriks et al, , 2017Busi et al, 2022); crystallite size, phase and texture (Sato et al, 2011(Sato et al, , 2021; and even lithium-ion batteries (Kamiyama et al, 2017). Additionally, it can non-destructively analyze archeological and cultural artifacts (Shiota et al, 2017;Cho et al, 2021). Conventional methods such as electron backscatter diffraction (EBSD) (Sadeghi et al, 2021), neutron and X-ray diffraction (Albertini et al, 2000), and metallographic etching methods have been reliably used for material characterization.…”

Bragg edge imaging using pulsed neutrons is a non-destructive technique for studying microstructure and texture of materials. It provides two-dimensional visualization of crystallographic information using a pixelated gas electron multiplier detector and a time-of-flight method. In this work, the properties of type 304 austenitic stainless steel samples were studied via Bragg edge imaging. The samples included hot-rolled, cold-rolled and heat-treated specimens, which were characterized to investigate texture, phase fraction and grain growth. The results showed that the crystallite size increased with increasing annealing temperature. The cold-rolled and annealed samples exhibited strong textures, while the hot-rolled sample showed no preferred orientation. The phase volume fraction of induced martensite in the cold-rolled sample was also obtained. Two-dimensional maps of microstructures and textures were obtained without destructive processes. The results were validated by electron backscatter diffraction and found to be consistent. This work provides valuable information for non-destructive characterization of bulk materials by performing Bragg edge imaging using the Hokkaido University compact accelerator neutron source.

The exploration of archaeological heritage aims at understanding past societies through the study of ancient materials. While archaeometric analysis provides valuable insights, invasive sampling raises ethical concerns and is often restricted, necessitating the development of non-invasive techniques. This study presents a methodology based on X-Ray Diffraction using synchrotron radiation. The approach involves the elaboration and characterization of model alloys, with X-ray data analysis using Rietveld refinement and Williamson-Hall plot method. Phase identification along with crystallographical investigations conducted on three medieval armours provides insights into manufacturing techniques and highlights the method’s limitation.
