    Opis:
    This work presents the metallographical observations of the chosen copper objects from the Late Middle Ages. Part of these studies is the analysis of metal relics from the Puck area conducted at the Faculty of Foundry, AGH-UST, in collaboration with the University of Warsaw. Medieval European cities were centers of trade and production of metal artifacts. Also in the Puck area, the manufacturing activities can be confirmed based on the metal findings. The aim of this study was to identify and systematize copper alloys used in the Late Medieval Period, on the basis of historic artifacts from Puck. The chemical composition analysis and microstructure observation were carried out. The research is at the first stage of an experiment of reconstructing the medieval alloys in order to study deeper their properties.

    Opis:
    The study was conducted for two selected 7xxx series aluminum alloys according to PN-EN 573-3:2010 – Polish version. The analysis of ingots was carried out on 7003, 7003S and 7010, 7010K alloys with a similar ratio of zirconium content. Symbols S and K are our internal modifications, still compatible with the standard. The ingots were made by semi-continuous casting. Aluminum alloys of this series, with improved properties, are intended for plastic-processing. The aim of this publication is to show how the microstructure of ingots is being formed during semi-continuous casting. The chemical profiles of ingots were determined using optical emission spectroscopy. Chemical analysis in micro-areas with evaluation by scanning electron microscope SEM with EDS analyzer was performed and the distribution of chemical elements in the microstructures are also presented. An XRD detector was used to show specific phases in the alloys. The grains are formed in a particular way during crystallization. In the middle of the ingot – further away from the crystallizer – the grains are larger. Semi-continuous casting together with homogenization enables the production of ingots with uniform cross sections as can be seen in the paper.
    Badania prowadzono dla dwóch wybranych stopów aluminium serii 7xxx zgodnie z PN-EN 573-3:2010 – wersja polska. Ocenę wlewków prowadzono na stopach 7003, 7003S oraz 7010, 7010K o zbliżonej zawartości cyrkonu. Oznaczenia S i K to modyfikacja wewnętrzna, nadal zgodna z normą. Wlewki wykonane zostały na drodze odlewania półciągłego. Stopy aluminium tej serii, o podwyższonych właściwościach, przeznaczone są do przeróbki plastycznej. Celem publikacji jest pokazanie, w jaki sposób kształtuje się mikrostruktura wlewków podczas półciągłego odlewania. Profile chemiczne wlewków wykonano przy wykorzystaniu optycznej spektroskopii emisyjnej. Wykonano również badania mikrostruktury wraz z analizą składu chemicznego w mikroobszarach z wykorzystaniem mikroskopu skaningowego (SEM) z analizatorem EDS oraz zaprezentowano rozkład pierwiastków na mikrostrukturach. Do wskazania konkretnych faz w stopach zastosowano detektor XRD. Ziarna podczas krystalizacji wlewków kształtują się w charakterystyczny sposób. Średnica ziaren zwiększa się w kierunku środka wlewka, wraz z oddalaniem się od krystalizatora. Półciągłe odlewanie w połączeniu z homogenizacją umożliwia wykonanie wlewków o jednolitym przekroju poprzecznym, co zostało zaprezentowane w pracy.

    Opis:
    High prices of tin and its limited resources, as well as several valuable properties characterising Cu-Sn alloys, cause searching for materials of similar or better properties at lower production costs. The influence of various nickel additions to CuSn10 casting bronze and to CuSn8 bronze of a decreased tin content was tested. Investigations comprised melting processes and casting of tin bronzes containing various nickel additions (up to 5%). The applied variable conditions of solidification and cooling of castings (metal and ceramic moulds) allowed to assess these alloys sensitivity in forming macro and microstructures. In order to determine the direction of changes in the analysed Cu-Sn-Ni alloys, the metallographic and strength tests were performed. In addition, the solidification character was analysed on the basis of the thermal analysis tests. The obtained results indicated the influence of nickel in the solidification and cooling ways of the analysed alloys (significantly increased temperatures of the solidification beginning along with increased nickel fractions in Cu-Sn alloys) as well as in the microstructure pattern (clearly visible grain size changes). The hardness and tensile strength values were also changed. It was found, that decreasing of the tin content in the analysed bronzes to which approximately 3% of nickel was added, was possible, while maintaining the same ultimate tensile strength (UTS) and hardness (HB) and improved plasticity (A5).

    Opis:
    The studied ingots were made of alloys with a similar zirconium ratio, typically be given as: EN AW-7010 [AlZn6MgCu] and EN AW-7003 [Al Zn6Mg0,8Zr], in accordance with European standard PN-EN 573-3:2014-02 English version. The symbols S and K are our internal modifications, compatible with the standard. The added zirconium was intended to improve the tensile strength resulting from plastic forming and an increasing resistance to cracking. Samples were taken from ingots made in the process of semi-continuous casting, some of which were homogenized; however, non-homogenized samples were also analyzed. The tests of tensile strength for the 7003, 7003S, and 7010K alloys were conducted longitudinally and transversely to the casting direction.The tensile strength test for 7010 was conducted only transversely to the direction of casting. The aim of this publication is to present the results of strength test sand to show a correlation between the basic properties of 7xxx-series aluminum alloys; i.e., relative elongation E, yield strength YS, and ultimate tensile strength UTS.
    Ocenę wlewków prowadzono na stopach o zbliżonej zawartości cyrkonu, zazwyczaj podawanych jako EN AW-7010 [AlZn6MgCu] and EN AW-7003 [AlZn6Mg0,8Zr], zgodnie z europejską normą PN-EN 573-3:2014-02 – wersja angielska. Obecne w pracy oznaczenia K, S to modyfikacja wewnętrzna zgodna z normą. Wprowadzony cyrkon ma za zadanie poprawę właściwości wytrzymałościowych stopów otrzymanych na drodze przeróbki plastycznej oraz zwiększenie ich odporności na pękanie. Próbki zostały pobrane z wlewków otrzymanych na drodze odlewania półciągłego, w stanie niehomogenizowanym i homogenizowanym. Badania wytrzymałości na rozciąganie przeprowadzano w kierunku podłużnym i poprzecznym w odniesieniu do kierunku odlewania stopów 7003, 7003S i 7010K. Dla stopu 7010 wytrzymałość na rozciąganie badano w próbie poprzecznej do kierunku odlewania. Celem publikacji jest prezentacja wyników badań właściwości wytrzymałościowych. Praca ma również na celu pokazanie korelacji pomiędzy podstawowymi właściwościami, tj. wydłużeniem względnym A, umowną granicą plastyczności Rp0,2 a wytrzymałością na rozciąganie Rm.

    Opis:
    Silicon bronzes are characterised by good mechanical properties and by high corrosion and mechanical wear resistance. The process of sleeve casting by means of the centrifugal casting with the horizontal axis of the mould rotation was analysed. The assessment of the influence of modification and centrifugal casting parameters on the microstructure and mechanical properties of alloys was carried out in the hereby work. Zirconium was applied as a modifier. Speed of rotation of the mould was the variable parameter of the centrifugal casting. The investigation results were summarised on the basis of the microstructure analysis and mechanical properties determination: UTS, proof stress, A10 and BHN. The experiment aimed at finding the information in which way the modification together with changing the pouring parameters influence the mechanical properties of the CuSi3Zn3FeMn alloy.

    Opis:
    This study characterizes the bronze jewellery recovered from the Lusatian culture urn-field in Mała Kępa (Chełmno land, Poland). Among many common ornaments (e.g. necklaces, rings, pins) the ones giving evidence of a steppe-styled inspiration (nail earrings) were also identified. With the dendritic microstructures revealed, the nail earrings prove the implementing of a lost-wax casting method, whereas some of the castings were further subjected to metalworking. The elemental composition indicates the application of two main types of bronze alloys: Cu-Sn and Cu-Sn-Pb. It has been established that the Lusatian metalworkers were familiar with re-melting the scrap bronze and made themselves capable of roasting the sulphide-rich ores. The collection from Mała Kępa has been described in terms of its structure and composition. The investigations were made by means of the energy dispersive X-ray fluorescence spectroscopy (ED-XRF), scanning electron microscopy (SEM) coupled with an energy dispersive X - ray analysis system (EDS) and optical microscopy (OM). In order to fingerprint an alloy profile of the castings with a special emphasis on the nail earrings, the data-set (ED-XRF, EDS) was statistically evaluated using multidimensional analyses (FA, DA).

    Opis:
    During the research a group of copper and tin alloys was investigated. The influence of variable additions of aluminium within the range of 0.3 – 1.4 wt % was analysed on tin bronze CuSn10 with the aim of obtaining durable bronzes, from outside the normalized copper alloy groups. Melts were conducted in order to obtain alloy samples for testing the chosen properties. Metallographic and SEM-EDS tests were carried out to determine the microstructure changes caused by introducing Al addition to CuSn10 alloy. Also, chosen mechanical properties were tested for the alloys investigated. The results showed considerable changes in the microstructure as well as significant hardening of the Cu-Sn alloys as the result of aluminium addition. The thermal and dilatometric analysis confirmed the presence of phase changes, also their parameters were assessed depending on the share of aluminium addition in the CuSn10. The aluminium additive applied within the range of 0.3-1.4 wt% to CuSn10 bronze clearly impacted the microstructure and the strength properties analysed, causing the increase in strength and hardness with simultaneous insignificant decrease of elongation of the CuSn10Al alloys.

    Cast axes are one of the most numerous categories of bronze products from earlier phases of the Bronze Age found in Poland. They had multiple applications since they were not only used objects such as tools or weapons but also played the prestigious and cult roles. Investigations of the selected axes from the bronze products treasure of the Bronze Age, found in the territory of Poland, are presented in the hereby paper. The holder of these findings is the State Archaeological Museum in Warsaw. Metallurgical investigations of axes with bushing were performed in respect of the casting technology and quality of obtained castings. Macroscopic observations allowed to document the remains of the gating system and to assess the range and kind of casting defects. Light microscopy revealed the microstructure character of these relicts. The chemical composition was determined by means of the X-ray fluorescence method with energy dispersion (ED-XRF) and by the scanning electron microscopy with X-ray energy dispersion analysis in micro-areas (SEM-EDS). The shape and dimensions of cores, reproducing inner parts of axes were identified on the basis of the X-ray tomography images. Studies reconstructed production technology of the mould with gating system, determined chemical composition of the applied alloys and casting structures as well as revealed the casting defects being the result of construction and usage of moulds and cores.

    Opis:
    Currently there is a constant development in the field of aluminium alloys engineering. This results from, i.a., better understanding of the mechanisms that direct strengthening of these alloys and the role of microalloying. Now it is microalloying in aluminum alloys that is receiving a lot of attention. It affects substantially the macro- and microstructure and kinetics of phase transformation influencing the properties during production and its exploitation. 7xxx series aluminum alloys, based on the Al-Zn-Mg-Cu system, are high-strength alloys, moreover, the presence of Zr and Sr further increases their strength and improves resistance to cracking. This study aims to present the changes of the properties, depending on the alloy chemical composition and the macro- and microstructure. Therefore, the characteristics in the field of hardness, tensile strength, yield strength and elongation are shown on selected examples. Observations were made on ingot samples obtained by semi-continuous casting, in the homogenized state. Samples were prepared from aluminum alloys in accordance with PN-EN 573-3: 2013. The advantage of Al-Zn-Mg-Cu alloys are undoubtedly good strength, Light-weight and resistance to corrosion. As widening of the already published studies it is sought to demonstrate the repeatability of the physical parameters in the whole volume of the sample.

    (Chełmno land, Poland) as it is reflected through casting workshop recovered during recent excavations. Among ready products, the ones giving evidence of local metallurgy (e.g. casting moulds and main runners) were also identified. With the shrinkage cavities and dendritic microstructures revealed, the artifacts prove the implementing a casting method by the Lusatian culture metalworkers. The elemental composition indicates application of two main types of bronzes: Cu-Sn and Cu-Pb. Aside these main alloying additions, some natural impurities such as silver, arsenic, antimony and nickel were found which may be attributed to the origin of the ore and casting technology. The collection from Kamieniec was described in terms of its structure and composition. The investigations were made by means of the energy dispersive X-ray fluorescence spectroscopy (ED-XRF), scanning electron microscopy (SEM) coupled with an energy dispersive X-ray analysis system (EDS) and optical microscopy (OM). In order to fingerprint either local or non-local profile of the alloys, the ED-XRF data-set was statistically evaluated using a factor analysis (FA).

    Arsenical copper has been used since 5th millennium cal.BC, later exchanged by application of Cu-Sn alloys in metallurgy. This work presents the results of metallographic and mechanical properties studies performed on two flat axes connected with local Eneolithic societies (4500-3000 cal.BC). The axes are one of the oldest metal artifacts from Polish land. Originally they were made from Cu-As alloy, and their chemical composition was established by X-ray fluorescence spectroscopy (XRF). Their microstructure was analysed using optical microscopy (OM) and scanning electron microscopy conducted with energy-dispersive X-ray spectroscopy (SEM-EDS). The macrostructure analysis (OM) of the axes was performed as well. On the basis of the results, the alloys used in the Eneolithic to cast the axes were reproduced in lab. In order to achieve the characteristics of the alloys, their mechanical properties including ultimate tensile strenght (UTS), hardness (HB), microhardness (HV0,1) and ductility were examined. The solidification process was studied by means of thermal analysis.

    Opis:
    During excavation of the cremation cemetery of urnfield culture in Legnica at Spokojna Street (Lower Silesia, Poland), dated to 1100-700 BC, the largest - so far in Poland – a collection of casting moulds from the Bronze Age was discovered: three moulds for axes casting made out of stone and five moulds for casting sickles, razors, spearhead and chisels, made out of clay. This archaeological find constituted fittings of foundrymen’s graves. In order to perform the complete analysis of moulds in respect of their application in the Bronze Age casting technology analytical methods, as well as, computer aided methods of technological processes were used. Macroscopic investigations were performed and the X-ray fluorescence spectrometry method was used to analyse the chemical composition and metal elements content in mould cavities. Moulds were subjected to three-dimensional scanning and due to the reverse engineering the geometry of castings produced in these moulds were obtained. The gathered data was used to perform design and research works by means of the MAGMA5 software. Various variants of the pouring process and alloys solidification in these archaeological moulds were simulated. The obtained results were utilised in the interpretation of the Bronze Age casting production in stone and clay moulds, with regard to their quality and possibility of casting defects occurrence being the result of these moulds construction. The reverse engineering, modelling and computer simulation allowed the analysis of moulds and castings. Investigations of casting moulds together with their digitalisation and reconstruction of casting technology, confirm the high advancement degree of production processes in the Bronze Age.
