Abstract: <div>Currently, the 8th edition of the "Implementation Doctorate" program is being implemented in Poland. This is a unique program on a global scale, the idea of which is that the program. [..] Read more

Abstract: <div>Simple material and mass balance were efficiently drawn in high carbon ferromanganese production processes based on simple calculations. However the prediction on different products in different reactive zones using a mathematical model using artificial intelligence nueral network has not been well conducted. [..] Read more

Abstract: <div>The processing of scrap metal as charge in steel furnaces is a relatively broad area, where many different processes and technologies are applied. One of these technologies is waste metal briquetting technology. [..] Read more

Abstract: <div>This paper is focused on the thermal properties of historical La Tène furnaces for the processing of iron ore. The technology itself has been used since 450 BC. [..] Read more

Abstract: <div>The submitted contribution is focused on the mathematical determination of temperature and thermal parameters depending on the heat removal from solidifying steel in the mould, respectively in the primary zone during continuous casting of steel. The main task of primary cooling is primarily the heat dissipation from solidifying steel, therefore the knowledge of temperature fields in the billet and mould is important. [..] Read more

Abstract: <div>The aim of the research in the hot metal desulfurization process is to create a mathematical model that will include both kinetic and thermodynamic aspects of the process. This is intended to increase the accuracy of predicting and obtaining the level of sulfur content in the hot metal, as well as to optimize process costs. [..] Read more

Abstract: The research deals with the evaluation of internal quality of zinc castings in terms of porosity. The castings were produced by high-pressure die casting from ZP0410 alloy, which is an alloy of zinc with addition of aluminium and copper. [..] Read more

Abstract: <div>The article concerns preliminary research involving the development of a flow model for a material consisting of a mixture of clay (70 %), quartz sand (10 %) and ceramic flour (20 %) in an upsetting test in order to determine the course of plasticizing stress as a function of actual strain. This material constitutes the mass for the production of ceramic roof tiles and, at the beginning of the process, it is pressed through forming tools, then cut to the appropriate size, stamped and dried.

Abstract: <div>Forging is currently one of the most economical processes for the manufacture of parts for industry. Product quality and production costs are very significant factors for manufacturers today and determines their competitiveness. [..] Read more

Abstract: <div>Due to the need to increase the efficiency and quality of production, expand the range of products manufactured and optimize the use of personnel, a project entitled: "Development of an integrated production system for the production of elements of reinforcement of modular structures of halls using modern construction materials at Adamietz Ltd. in Strzelce Opolskie” was undertaken.

Abstract: <div>Cardan shafts are a system widely used for power transmission in the industrial area, especially in the automotive sector. This study carried out computer-aided design and analysis of the involute profiled spline shaft (cardan shaft) and hub assembly. [..] Read more

Abstract: <div>The article deals with the first results from the so-called laboratory exposure loop after 10,000 h operation. This loop is an experimental setup that allows the selected material to be exposed to the conditions that prevail in the boiler of a coal-fired power plant or incineration site. [..] Read more

Abstract: <div>This paper focuses on the effect of contact force on dynamic electrical resistance in resistance spot welding which effects amount of heat generated in time. Methods for welding parameters monitoring and signal processing are presented. [..] Read more

Abstract: <div>The paper deals with the manufacturing of thin walls by various additive technologies. CMT- and microMAG-based WAAM (Wire Arc Additive Manufacturing) and LMD (Laser Metal Deposition) were selected as representatives to produce thin walls. [..] Read more

Abstract: <div>The presence and importance of cavitation damage and fracture during creep of Cr-Mo-V creep resistant steels (including martensitic grades) increases with increasing temperature and time to fracture, and at the same time, a decrease in fracture elongation can also be observed. In the case of uniaxial creep tests, the area and distance from the fracture line where the cavitation can be detected while its intensity gradually decreases also increases.The creep cavitation behaviour of P91 and P92 steels was monitored in a series of creep tests performed in the temperature range of 575 to 625 °C and with a time to fracture of up to 35,000 hours. [..] Read more

Abstract: <div>The article presents results of a complex wear analysis of forming tools in the process of band extrusion for ceramic roofing tiles. The materials for such tools must be especially resistant to abrasive wear, which occurs because of contact with the extruded ceramic mass band, which consists mostly of clay (70 %), quartz sand (10 %) and flour from ceramics recycling (20 %). [..] Read more

Abstract: <div>The article determinates the operating temperature of forging tools intended for the hot precision forging process of a selected series of die forgings, with respect to the operational durability of the forging equipment. The durability of forging tools is one of the important aspects affecting the price of the final product in the form of a forging, especially in the case of a small forging, up to 45 %.

Abstract: <div>Nowadays, high-strength steels (HS) and ultra-high-strength steels (UHS) are increasingly used, especially in welded structures. These types of steels are mainly used as material for heavily loaded structures such as bridges, cranes, and excavators, as well as for pressure vessels, various types of vehicles, ships, drilling structures, etc. [..] Read more

Abstract: <div>This contribution introduces a comprehensive methodology for evaluating cold spray coatings using scratch testing technique. Unlike traditional thermal spray coatings, cold spray coatings have not been systematically and thoroughly scratch tested, leading to a lack of experimental data and evaluation methods.

Abstract: Plasma electrolytic oxidation (PEO) technique is a process of surface treatment of light metallic materials such as magnesium alloy, to produce coatings increasing the corrosion resistance. In this work, the effect of direct or alternating current deposition mode on the structure and corrosion behavior of PEO coatings on Mg substrates prepared by powder metallurgy (PM) was studied.
