The production of Nuragic Bronze Figurines represents a unique opportunity to provide key information not only about the iconography but also the metal production and casting techniques of such a class of objects. The period of their production is principally Early Iron Age (XI-VII century BC) in Sardinia, Italy. We propose to analyse 4 archaeological artefacts (a navicella and 3 knives) and 6 small foundry residuals by using neutron diffraction. The data obtained through this technique will give us detailed information about the phase composition of the metal matrix and the non metallic phases present, which originate from metal smelting or mineralization. Moreover, the microstructural analysis performed on the metal phase will lead to a better comprehension of the metallurgical processes through the determination of texture, grain size and residual strain density and distribution.
