Abstract: This paper is focused at increasing the efficiency of the supply and demand chain in a company engaged in the assembly and production of individual components for the automotive industry. Each company uses different tools to increase its competitiveness. [..] Read more

Abstract: During the pressing of sheet metal parts, cracks may form around the holes that weren't predicted by numerical simulations. These cracks are caused by the partial depletion of the forming capacity at the edges of the hole due to the preparation technology used, most often shearing. [..] Read more

Abstract: Military filters introduced in the Army of the Czech Republic are most commonly used when working with combat equipment and weapons and in manoeuvring activities in the terrain with the use of explosives or chemical warfare agents. During such activities, a large number of pollutants in the form of nanoparticles are released. [..] Read more

Abstract: The iron and steel metallurgy produces significant quantities of solid, liquid and gaseous wastes. The solid wastes like dusts, sludges and mill scales have been stored in dumping area due to their chemical composition, mainly by high content of zinc, cadmium, lead or organic compounds contamination. [..] Read more

Abstract: Top-gas dedusting at blast furnaces (BF) is usually done with venturi scrubbers. However, in recent years, the total dry dedusting of BF top-gas has become a common technology. [..] Read more

Abstract: Ferritic-martensitic Eurofer-97 and oxide dispersion strengthened (ODS) Eurofer steels are potential candidates for structural applications in advanced nuclear reactors. Influence of scandium, yttrium, and aluminum addition was studied at 600 °C using 10-6 wt.% oxygen concentration. [..] Read more

Abstract: Nanoindentation methods used for evaluation surface layers are static indentation and scratch indentation too. Static indentation methods are used namely for evaluation hardness characteristics and for evaluation elastic deformation and plastic deformation of surface layers too based on measurement indentation curves – dependence depth indentation and normal force during all indentation process during loading and unloading.

Abstract: The paper presents the possibility of using the ImageJ computer program for image analysis as a method of assessing the proportion of sample surfaces occupied by corrosion. The program allows to calculate the size of any graphic selection and calculates the number of pixels contained in it, can also measure distances and angles between points or elements of images. [..] 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: Currently, there is increasing pressure to reduce waste generation and to use it as a secondary raw material. In the framework of this work, there are presented beginning parts of the project plan called "Research of processing of metallurgical waste, materials and by-products from metallurgical and related operations number CZ.02.1.01/0.0/0.0/17_049/0008426“. [..] Read more

Abstract: Crack initiation of the ferritic martensitic steel T91 and austenitic steel 316L is currently under study. This is due to the evaluation ongoing in the EC for materials compatibility in Heavy Liquid Metals (HLM) environment, and, in particular, the issue of Liquid Metal Embrittlement.Slow Strain Rate Tensile (SSRT) tests were performed with flat specimens in PbBi at 300°C with oxygen content in the range of about 10-6 wt.% down to 10-12 wt.% and, for comparison in air, up to the point of maximal stress (without or with minimum necking). [..] Read more

Abstract: The development of Generation IV nuclear reactors and accelerator driven systems (ADS) is supporting a wide range of work on the compatibility of stainless steels with heavy liquid metals (HLM).The austenitic steel DIN 1.4970 (also known as 15-15Ti) is being qualified for use in heavy liquid metals because of its lack of sensitivity to Liquid Metal Embrittlement. The aim of this study is to look into cracking modes and their main characteristics in order to reach a clear idea of mechanisms.Flat tensile, tapered specimens were loaded in PbBi at 300 °C with low oxygen content and, for comparison in air, up to the Ultimate Tensile Stress, UTS, point and rupture. [..] 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: The ferritic martensitic steel T91 is among the candidate materials for internal structural components of future Heavy Liquid Metal cooled reactors. The position of T91 on the list of the candidate materials is now being questioned due to the evidence of its sensitivity to liquid metal embrittlement (LME), mainly in PbBi eutectic. [..] Read more
