| Outline of Final Research Achievements |
This research has demonstrated technical applicability of synchrotron high-energy X-ray fluorescence (SR-HE-XRF) analysis for possible provenance study of ancient iron/steels and also synchrotron X-ray micro computed tomography (CT) for their non-destructive technical examination using iron/steel objects unearthed at an archaeological site in Central Anatolia, the Hittites' heartland.
The SR-HE-XRF analyses undertaken at BL08W, SPring-8, revealed that the vast majority of iron/steel objects contain heavy metals such as barium and lanthanum. Furthermore, SR-HE-XRF mapping illustrated that the distribution patterns of these heavy metals are not necessarily identical, which indicates they were contained in the objects in a different way. Also, the synchrotron X-ray micro-CT imaging conducted at BL20B2 successfully provided reconstructed images sufficient for the identification of distribution patterns of slag inclusions being important for technical examination especially about forging.
