摘要：Traces of a diversified settlement system of the middle and late La T¨¨ne period were found recently in South-West Hungary. The site of Ordacsehi-Cseref.ld is one of the most important sites of Celtic settlements of the Carpathian Basin due to its 26 buildings, kiln for baking pottery, further objects and its findings of local iron forging. Ten slag samples, nine iron tools and a bloom with slag from the mentioned site were examined by our research team. The main objectives of examinations were to reveal the material and structural properties of the slag and metal items, the definition of the metallurgical functions of the different pieces of slag, the exploration of the traces of processing and probable heat treatments on the iron tools in order to characterize the technology of local smithing. Most of the examined slags are probably the by-product of the purification in an oxidizing atmosphere intended to separate the slag from the iron after reheating the bloom. The iron tools are of medium quality, generally made of relatively mild, ferritic, ferritic-perlitic material. However one of the tools has heterogeneous structure containing constituent (martensite) with extreme hardness. The grain size, settlement of inclusions and position of layers containing different volume of perlite served information about the technology of forming. Although the examined iron tools were made from the same bloom by objects, by taking advantage of the heterogeneity of the bloom, they could modify the distribution of carbon in the structure with the help of forging technique when forming edges and points. The planned use usually influenced the forming of the tool
