Abstract

As part of a research project on Sardinian bronze metallurgy, neutron diffraction and neutron imaging experiments were performed on a set of Nuragic bronzes at the ISIS Neutron and Muon Source (Didcot, UK). Neutron based techniques are a very effective tool for the study of archaeological samples: neutron diffraction provides important information regarding the composition, the microstructure and the conservation status of metallic materials; while neutron imaging provides information about the structure and the morphology of the given samples. These data are of great value and, when compared with archaeological information, they can add new and different insights about the investigated artefacts. Furthermore, from data analysis, it is possible to answer some unresolved questions about the artefacts, such as their effective use and their manufacturing procedure. In this work, we present the results of the analysis of a bronze dagger.
