Title Neutron strain scanning of archaeological bronzes
Abstract We report neutron strain scanning experiments on archaeological bronzes, with the aim of identifying the original manufacturing techniques used. The specimens studied were a Picenan necklace from VI BC, and an Etruscan bucket handle from IV BC, exhibited at the Marches Museum of Archaeology, Ancona, Italy. Time-of-flight neutron diffraction and transmission experiments were performed at the ENGIN-X instrument, ISIS, UK. For the necklace, characteristic bending strain profiles and a small degree of preferred orientation indicate that the specimen had been cold worked. For the handle, broad diffraction peaks and highly distorted Bragg edges -typical of a columnar grain microstructure- suggested that this specimen was cast and did not undergo significant thermal or mechanical treatment. The relation between the experimental diffracted and transmitted time-of-flight spectra, and the microstructure of specimens are discussed.
