Abstract: Current tin recovery processes from steel sheets of scrapped cans are mainly based on hydrometallurgical methods using water solutions of acids and bases. Due to the universally binding tendency forcing activities aimed at improving the efficiency of production processes, also in the case of hydrometallurgical methods of metal recovery, it is necessary to look for new economic technological solutions.

Abstract: The AZ31/6060 bimetallic material was fabricated through compound casting, which involved pouring AZ31 magnesium alloy heated up to 660 °C onto a 6060 aluminum alloy insert placed in a steel mould, both preheated to 300 °C. The microstructural analysis was performed with an optical microscope (OM) and a scanning electron microscope equipped with an energy-dispersive X-ray spectrometer (SEM–EDS). [..] Read more

Abstract: The main advantage of mechanical alloying (MA) is a possibility to combine together different components that are difficult or even impossible to combine by conventional melting methods due to their high reactivity in liquid or semi-liquid state. In the present work, results of experiments performed on Al-AgO and Al-CeO2 composite rods manufactured by means of mechanical alloying method was presented. [..] Read more

Abstract: Nowadays, manufacturing of materials with unique properties is in the centre of attention of materials engineering. Aluminum and aluminum alloys are widely applied in variety of industries due to their high specific strength and in the following years they will become even more important. [..] Read more

Abstract: HCM in Miasteczko Śląskie is the only zinc smelter in Europe which use Imperial Smelting Process technology. Paper shows ISF charging model which allows to calculate on-line current state of the furnace batch parameters. [..] Read more

Abstract: One of the currently used industrial methods of zinc and lead production is Imperial Smelting Process, based on the use of a shaft furnace. It was created for the processing of traditional minerals of both metals that form compounds with sulfur. [..] Read more

Abstract: Aluminum alloys show a high strength-to-weight ratio and a relatively good corrosion resistance making them prospective structural materials in many fields. In material standards of commercial Al alloys, chemical composition is always defined as concentration ranges of alloying elements and impurities. [..] Read more

Abstract: Zn-based alloys are widely used mainly as a protective coating in corrosive environments. Therefore, their research is mainly focused on their corrosion resistance properties and less effort is devoted to the study of mechanical properties, particularly to potential defects under mechanical load in certain applications.The aim of this paper is to characterize the cracking behaviour of three coatings: Zn, Zn5Al and Zn5Al0.5Mg on a steel substrate before and after plastic deformation.

Abstract: The paper presents the results of physical modelling of the process of rolling AlZn5.5MgCu aluminum alloy bars on a three-high reeling mill. Tests were carried out in a complex strain state (simultaneous torsion with compression) using an STD 812 torsion plastometer. [..] Read more

Abstract: This study reports an alternative route for obtaining crystalline metal boride composite powders at low temperatures using various chemical reactions. The ternary system of Co-Ni-B was studied by using anhydrous metal chlorides and sodium borohydride powder mixtures. [..] Read more

Abstract: Metastable β-titanium alloys are receiving much interest for various applications such as aircraft industry and medicine thanks to their excellent mechanical properties and biocompatibility. The common way of preparing the titanium alloys is hindered by its production costs. Powder metallurgy (PM) approach is a promising route for cost-effective fabrication of titanium alloys due to possibility of near net shaping.In this study, binary biomedical Ti-15Mo alloy was prepared by PM. [..] Read more

Abstract: Powder bed techniques of additive manufacture, where the built product is surrounded by a loose powder, yield low-quality surfaces. The powder particles that are in a close contact with the product adhere to its surface, either by thermal diffusion effects or by partial melting by contour scan tracks. [..] Read more

Abstract: Sintered permanent magnets based on the Nd2Fe14B intermetallic compound are widely used in industry as a rule in a temperature range of from -60 to 150 °C. However, in recent years, there appears a need to use such magnets at cryogenic temperatures and mainly at liquid nitrogen temperature (77 K). [..] Read more

Abstract: In recent years, the application of various additions (hydrides, oxides, intermetallic compounds, etc.) in powder mixtures for manufacturing Nd-Fe-B magnets shows promise as the method that allows one to increase the hysteretic characteristics of the magnets at the expense of realized grain-boundary diffusion and grain-boundary structuring processes. The processes allow one to introduce both the heavy rare-earth metals and copper that was shown also to favour the increase in the hysteretic parameter of Nd-Fe-B-based compositions. [..] Read more

Abstract: Paper presents characteristics of thermovision, 3D scanning and tomography methods used for quality rating in multilayer ceramic moulds used for purposes of aircraft turbine blades casting. Moulds measurements were performed with thermovision camera, 3D scanner and tomography. [..] Read more

Abstract: Computed Tomography (CT) as a known medical research method is nowadays widely used in research institutions and production companies. Due to its nondestructive testing nature, CT finds application in both final product quality control such as castings or CNC machined parts and research of new materials, e.g. [..] Read more

Abstract: One of the most crucial parameters having deciding influence on the quality of multilayer ceramic forms used in precision casting process of aircraft blades, is their thickness. Traditional measuring methods ensure a possibility of quantitative determining the factor only after inundating the form with liquid metal and breaking it. [..] Read more
