This research work gave new results on the historical studies and the technological levels of different ages. The examination of metallic artifacts has a great importance in this work. The answers to our questions on the structure of metals are continuously searched for by means of new measurement methods. Optical microscopy and classic metallography have a significant role in the research projects of the mentioned area. Nowadays it is not necessary to use complicated etching methods to study the different metallographic phases. SEM-EDS studies of the same sample provide information on the chemical composition of the phases, and it is possible to examine the structure at higher magnification. This study summarizes the amount of information obtained from the project, and the practice of the Archaeometallurgical Research Group of the University of Miskolc (ARGUM), based on these measurement methods. Selected examples are used to show the in-depth analysis of the microstructure. Metallography is a destructive material testing method, as samples must be taken from the artifacts. Questions of heritage protection and restoration arise. In all cases, the balance between the amount of information and the restoration or protection must be considered.

By this method, the taking of optical microscopic and electron microscopic images become possible about the same experimental area in an appropriate hardware-software environment. In the aluminium-manganese alloys, precipitation form during homogenization which is one of the processes in the rolling technology sequence. The features, morphology and composition of developing precipitation depend on the homogenisation temperature and time, these characteristics change within wide limits. In this study, the precipitates forming during homogenization were examined by correlative method. In 3003 manganese alloy, the appearance of particles at different homogenization temperature and time was followed. The microstructure of sample before and after homogenization was investigated, the phases were identified in the microstructure and the formation processes were followed.

The concentration of Si, Zn and the Mn were varied within the standard specification. Not only the temperature but the holding time of homogenization was also varied. The effects of alloying element on the precipitation process during the homogenization were investigated by optical and scanning electron microscopy. The correlative microscopy was also a very useful method to follow the evaluation of different precipitate. Hot and cold compression tests were used to detect the effect of different precipitation on the formability. It was experimentally showed that just a slight difference in the alloying elements resulted in significantly different microstructure and formability after the same homogenization process.

In addition, a related Avar settlement dating from the 7th to 9th centuries was also unearthed, with remains of carriage‐roads, about twenty houses with stone furnaces and a number of open-air furnaces. The bloomery remains fit into the series of furnaces of the 7th and 8th centuries found previously on other sites in former Pannonia. As a part of a complex research project, more than a hundred slag samples from Zamárdi were examined by XRF, ICP, XRD and SEM-EDS. Different slag types and their metallurgical roles were identified. We concluded that the nature of archaeometallurgical sites can be confidently determined by the typological examination of several kinds of slag.

The majority of archaeometrical research is carried out by the related institutes at the University of Miskolc, but other research organisations were also involved. A fundamentally archaeometrical objective of the project is to perform a complex materials testing of the archaeological finds that completely cover the fields of the professional activities of Avar Age ironworking, as well as ceramic production, plant and animal remains. The research programme is based on the unique Avar archaeological sites of Zamárdi-Kútvölgy and KaposvárFészerlak, where iron metallurgical centres were found. The general aim of our research programme is to gain a better understanding of Avar Age iron production technology and the artisans' environmental knowledge both in a national and international context. By analysing archaeological, technological, archaeometrical and archaeometallurgical data, we try to reconstruct Avar Age iron production from the preparation of ores to the formation of iron artifacts. This study presents the materials testing of the slag finds and iron artefacts (chemical analysis (XRF, ICP), macro- and microstructural analysis (OM, SEM-EDS), mineralogical analysis (XRD)) as well as ceramic petrographic and archaeobotanical analyses. Different slag types and their metallurgical roles, as well as the fundamental manufacturing processes, applied by the Avars, were identified. We concluded that the nature of archaeometallurgical sites can be confidently determined by the typological examination LA - Hungarian DB - MTMT ER -
