Opis:
A significant part of the knowledge used in the production processes is represented with natural language. Yet, the use of that knowledge in computer-assisted decision-making requires the application of appropriate formal and development tools. An interesting possibility is created by the use of an ontology that is understandable both for humans and for the computer. This paper presents a proposal for structuring the information about the foundry processes, based on the definition of ontology adapted to the physical structure of the ongoing technological operations that make up the process of producing castings.

Opis:
The article presents research results performed on aluminum bronze CuAl10Fe5Ni5 (BA1055) castings used for marine propellers. Metallographic studies were made on light microscope and a scanning electron microscope to assess quantitatively and qualitatively the alloy microstructure. It has been shown that the shape, size and distribution of the iron-rich κ−phase precipitates in bronze microstructure significantly affect its mechanical properties. With an increase in the number of small κ−phase precipitates increases the tensile strength of castings, while the presence of large globular precipitates improves ductility. Fragmentation and shape of κ−phase precipitates depends on many factors, particularly on the chemical composition of the alloy, Fe/Ni ratio, cooling rate and casting technology.

Opis:
One of the most interesting categories of artifacts for archaeometallurgical research includes deposits of bronze items, so-called “metallurgists hoards”. They contain, aside of final products, many fragments of raw material and, moreover, metallurgical tools. An important source for the studies on the history of metallurgical technology is hoard from Przybysław, Greater Poland district. Thus, the aim of the work is the identification and interpretation of bronze-working practices and strategies adopted by prehistoric communities of the Late Bronze Age and the Early Iron Age (ca. 600 BC). The examined objects are characterized in terms of their design, structure, and chemical composition. The methods chosen for the studies of artifacts include: metallographic macro- and microscopic observations using optical microscopy (OM) and scanning electron microscopy (SEM), the analysis of chemical composition with the methods of energy dispersive X-ray spectroscopy (EDS), and X-ray fluorescence (ED-XRF). The thermodynamic analysis of the alloys was performed on the basis of the CALPHAD method. The experimental melts allowed to verify the theoretical considerations and to determine the characteristic temperatures of changes. The old casting technology can be analyzed basing on computer modeling and computer simulation methods. Simulations in the MAGMASOFT® software are a good example to illustrate how to fill a mould cavity with a molten bronze for a hoop ornament. It is also an appropriate tool to determine temperature distribution in a mould. The simulations also show the possible disadvantages with this old technology.

Opis:
The mold temperature of the downward continuous unidirectional solidification (CUS) cannot be controlled higher than the liquidus of alloys to be cast. Therefore, the continuous casting speed becomes the main parameter for controlling the growth of columnar crystal structure of the alloy. In this paper, the tin bronze alloy was prepared by the downward CUS process. The microstructure evolution of the CUS tin bronze alloy at different continuous casting speeds was analysed. In order to further explain the columnar crystal evolution, a relation between the growth rate of columnar crystal and the continuous casting speed during the CUS process was built. The results show that the CUS tin bronze alloy mainly consists of columnar crystals and equiaxed crystals when the casting speed is low. As the continuous casting speed increases, the equiaxed crystals begin to disappear. The diameter of the columnar crystal increases with the continuous casting speed increasing and the number of columnar crystal decreases. The growth rate of columnar crystal increases with increasing of the continuous casting speed during CUS tin bronze alloy process.

Opis:
An attempt to examine the earliest traces of non-ferrous metal metallurgy and casting in present-day Krakow has been made. The preparatory investigation has centred around a group of finds coming from a small section of the eastern part of the city, the area of Nowa Huta. The paper gives an overall view of objects ranging from the first copper artefacts from the territory of Poland in the 4th millennium BC through Lusatian bronzes and Celtic products to modern slag from Jan Thurzo’s copper smelter. The analysis, involving diverse copper or copper alloy artefacts, ornaments and tools – both imports and local products – has been aimed at preliminary identification of Krakow’s earliest metal artefacts in terms of their materials and methods of production, and at preparing the ground for further study. This multifaceted research is intended to result in a comparison of materials and techniques used in metallurgy and casting during the timespan of 5000 years.
Podjęto próbę zbadania najstarszych śladów metalurgii i odlewnictwa metali nieżelaznych na terenie dzisiejszego Krakowa. Do pierwszych badań wybrano znaleziska z niewielkiego obszaru we wschodniej części Krakowa, obejmującego rejon Nowej Huty. Przedstawiono pierwsze zabytki miedziane z ziem polskich z IV tysiąclecia p.n.e., brązy kultury łużyckiej, wyroby celtyckie, aż po nowożytny żużel z huty miedzi Jana Thurzo. Do analizy wybrano zabytki miedziane i wykonane ze stopów miedzi, ozdoby i narzędzia, będące zarówno importami, jak i przedmiotami wykonanymi na miejscu. Celem pracy była wstępna identyfikacja materiałów, z których wykonano najstarsze zabytki metalowe odnalezione na terenie Krakowa, ustalenie technik wytwórczych, dzięki którym powstały, a także przygotowanie dalszych badań w tym zakresie. Rezultatem wielopłaszczyznowych badań będzie porównanie stosowanych surowców i materiałów oraz technik metalurgicz nych i odlewniczych na przestrzeni pięciu tysięcy lat.

Opis:
The paper presents the results of research aimed at developing assumptions for the preparation of a charge in the form of fine scrap copper alloys (chips/shells) guaranteeing effective removal of impurities and obtaining a metal bath of the required metallurgical quality. The tests were conducted for tin-zinc-lead bronze of the CC499K grade. As part of the work, the characteristics of this type of waste available on the market were made in terms of quality and the possibility of their use for the production of both alloys and finished products, taking into account the elimination of harmful impurities that may ultimately affect the production process adversely. The subject of the work was the selection of appropriate waste cleaning methods in the form of an oily shell in the CC499K (CuZn5Sn5Pb2) grade and its drying in terms of increasing the use of impure waste from machining as scrap for direct melting. The waste was assessed in relation to individual parameters. The research was carried out on 3 groups of waste, with varying degrees of moisture.

Opis:
Casting is one method of making metal components that are widely used in industry and up to date. The sand casting method is used due to its simplicity, ease of operation, and low cost. In addition, the casting method can produce cast products in various sizes and is well-suited for mass production. However, the disadvantage of casting, especially gravity casting, is that it has poor physical and mechanical properties. Tin bronze Cu20%wt.Sn is melted in a furnace, then poured at a temperature of 1100°C into a sand mold. The cast product is a rod with 400 mm in length, 10 mm in thickness, and 10 mm in width. The heat treatment mechanism is carried out by reheating the cast specimen at a temperature of 650°C, holding it for 4 hours, and then rapid cooling. The specimens were observed microstructure, density, and mechanical properties include tensile strength and bending strength. The results showed that there was a phase change from α + δ to α + β phase, an increase in density as a result of a decrease in porosity and a coarse grain to a fine grain. In addition, the tensile strength and bending strength of the Cu20wt.%Sn alloy were increased and resulted in a more ductile alloy through post-cast heat treatment.

Opis:
Small additions of Cr, Mo and W to aluminium-iron-nickel bronze are mostly located in phases &kappa i (i=II; III; IV),and next in phase &alpha (in the matrix) and phase γ2. They raise the temperature of the phase transformations in aluminium bronzes as well as the casts’ abrasive and adhesive wear resistance. The paper presents a selection of feeding elements and thermal treatment times which guarantees structure stability, for a cast of a massive bush working at an elevated temperature (650–750°C) made by means of the lost foam technology out of composite aluminium bronze. So far, there have been no analyses of the phenomena characteristic to the examined bronze which accompany the process of its solidification during gasification of the EPS pattern. There are also no guidelines for designing risers and steel internal chill for casts made of this bronze. The work identifies the type and location of the existing defects in the mould’s cast. It also proposes a solution to the manner of its feeding and cooling which compensates the significant volume contraction of bronze and effectively removes the formed gases from the area of mould solidification. Another important aspect of the performed research was establishing the duration time of bronze annealing at the temperature of 750°C which guarantees stabilization of the changes in the bronze microstructure – stabilization of the changes in the bronze HB hardness.

Opis:
The article presents tests on a new lead-free bronze CuSn4Zn2PS, intended for fittings for contact with drinking water, in which the addition of lead was replaced with sulphur. The subject of the experimental work was the production of semi-finished products from this alloy based on the charge coming entirely from waste generated after machining. A specialized pilot line was used for the tests, and after cleaning, the waste was melted and then were continuously cast in the form of rods and hollow rods. The cleaning efficiency was assessed, and the manufactured semi-finished products were subjected to tests, including the assessment of the chemical and mechanical homogeneity and the structure of the test batch of the semi-finished casting products in terms of the possibility of manufacturing products meeting the requirements of technical specifications. The obtained results, both in terms of a stable chemical composition, homogeneous and reproducible mechanical properties, fully compliant with the specifications for fittings bronzes (CC499K), as well as the lack of faults of the obtained semi-finished products, despite a very large share of waste material, indicate the possibility of using the tested recycling method for the production of semi-products of sulphur bronze, which is an alloy that is relatively difficult to manufacture.

Opis:
Non-destructive testing methods are widely applied for metal artefacts research. The analyses presented here are part of research and conservation program encompassing metal artefacts discovered during archaeological excavations in the years 2010–2011 in the area of Czermno. Among metal artefacts of archaeological origin there is an important group of objects connected with cult. Reliquary crosses called encolpions can be distinguished here; worn both by priests and by lay people in Central and Eastern Europe. They present an interesting group for historical and iconographic research, as well as for the analyses of the materials and the techniques applied. The type of cast encolpions were examined, found in the area of the old dwelling complex connected with fortified settlement of Czermno (the old Grody Czerwieńskie). These objects are initially dated to the 12th century. These metal artefacts are researched, by application of the non-destructive testing methods, at the Faculty of Foundry Engineering of the AGH University of Science and Technology in Kraków in cooperation with Maria Curie-Skłodowska University in Lublin, the Polish Academy of Sciences and the Rzeszów University. The research helped to enlarge the scientific scope of knowledge on Mediaeval materials and manufacturing techniques, while the conservation efforts gave back the proper artistic value to the artefacts from Czermno and allowed for the appropriate exhibition.

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.

Opis:
The casting workshop in Grzybiany is one of the most important archaeological sites in regards to casting technology from the Bronze and Early Iron Ages. During the "Grzybiany. Osada nadjeziorna z epoki brązu i żelaza" [Grzybiany. Lakeside settlement from the Bronze and Early Iron Ages] research, the structure of casting moulds was analyzed as well as the chemical composition and microstructure of one of the more-interesting metal artefacts found within the workshop. Based on this, geometric visualization was performed with the help of computer-modeling methods. For scientific, experimental, and educational purposes, reconstruction of a zoomorphic pendant was performed using the lost-wax method. Wax models injected into a matrix were used, along with fired ceramic (gypsum) moulds and a specially prepared modeling alloy that corresponds to the original material. In this way, a true replica of the original was obtained: technologically, structurally and chemically. Studies of production technology of the casting workshop dated back to the Bronze and Early Iron Age help to increase the knowledge of the mould-preparing technology and the alloys used. Modern tools and computer programs aid in the research of old technologies and help disseminate the results.
Pracownia odlewnicza w Grzybianach należy do jednego z najważniejszych stanowisk archeologicznych pod względem studiów nad technologią odlewniczą w epoce brązu i wczesnej epoce żelaza. W toku prac wykonano analizę struktury form odlewniczych. Przeprowadzono także analizę składu chemicznego i mikrostruktury jednego z ciekawszych zabytków metalowych, odkrytych na terenie pracowni. Na tej podstawie, z wykorzystaniem metod modelowania komputerowego, wykonano wizualizację geometryczną. W celach naukowych, doświadczalnych i edukacyjnych wykonano rekonstrukcję zawieszki zoomorficznej przy wykorzystaniu metody wytapianych modeli. Zastosowano modele woskowe wtryskiwane do matrycy, formy ceramiczne (gipsowe) wypalane oraz specjalnie przygotowany stop modelowy, odpowiadający oryginalnemu. W ten sposób uzyskano wierną technologicznie, strukturalnie i chemicznie replikę zabytku. Badania technologii produkcji warsztatu odlewniczego z epoki brązu i wczesnej epoki żelaza przyczyniają się do wzrostu świadomości o stosowanych technikach przygotowania form i wykorzystywanych stopach. Współczesne narzędzia i techniki komputerowe wspomagają badania dawnych technologii i służą ich upowszechnianiu.
