“…12b). Cementite needles have been observed in other studies [4,44] and can be formed after the precipitation of proeutectoid cementite (brittle) on austenitic grains boundaries during manufacturing processes [4,42]. The numerous clusters of cementite needles observed at high spatial resolution, which are formed by the diffusion of carbon during the ageing process [43], did not correspond to our object.…”

The smithing skills of craftsmen in the western Mediterranean during the early Iron Age can be determined by studying the microstructure of oxidised iron items. While some ghost structures have already been identified in dense corrosion products, their formation has not always been explained. Four objects from southern France were analysed using optical microscopy, X-ray diffraction, micro-Raman spectroscopy and field-emission scanning electron microscopy coupled with energy dispersive spectroscopy and electron backscatter diffraction. The role of microstructure, grain boundaries, cracks, species diffusion through oxides in soil corrosion and the initial microstructure are discussed. An additional parallel degradation mechanism (graphitisation) was experimentally revealed.
