  • The study of sword forging techniques, and their evolution with time, is one of the mostinteresting topics in the analysis of the Japanese blade-forging methodology. The investigationabout the evolution of shape and manufacturing techniques of Japanese swords is a very wellestablished field of study. However, this has been mostly based on standard punctualanalytical techniques, like for example metallography, while this field is still lacking anexperimental technique allowing to characterize, quantitatively and in a non-invasive way, thevarious crystal phases present in the artefacts. Thermal neutron diffraction, thanks to the highpenetration power of neutron, can overcome this limit. Six fragments of blades, pertaining tothe five Koto Age (10th - 11th century AD) forging traditions, and two more recent ones havebeen measured by this technique. In addition, the investigation was extended to two intactJapanese long swords again from Koto Age. All measurements were carried out through timeof flight neutron diffraction to quantitatively analyze the phase composition. The carboncontent, the martensite presence, the conservation status and the amount of the crystalline partsin the slag inclusions were determined. Moreover, experiments aiming to determine stress andstrain distribution in selected parts of the blades were performed on the two intact Japaneseswords to evidence possible similarities and differences between the two forging traditions.
