Abstract: Flake zinc-aluminium coatings are used in industry for decades. They can perform high corrosion resistance according to required accelerated tests, but in the field application the corrosion resistance is reduced due to nonuniform thickness of coating layers. [..] Read more

Abstract: One of the intensively studied issues regarding hydrogen embrittlement of advanced high strength steels (AHSS) is the absorption and diffusion of hydrogen produced by atmospheric corrosion. Scanning Kelvin Probe (SKP) is a tool sensitive enough to detect low amounts of hydrogen formed during atmospheric corrosion. [..] 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: From the large number of available metals with the memory of shape only a few of them found clinical application. Biocompatible orthodontic wires, applied in case of false occlusion reconstruction, are made of intelligent materials and components. [..] Read more

Abstract: Due to the high biocompatibility of magnesium, magnesium based alloys are considered as suitable materials for the production of biodegradable implants such as the fixators of fractured bones or stents. The main insufficiencies of pure magnesium are lower yield and ultimate strength and high corrosion rate. [..] Read more

Abstract: Magnesium and its alloys are promising materials that have potential mainly in the field of transport (e.g. automobile industry) and medicine (e.g. [..] Read more

Abstract: Corrosion and material selection are critical challenges in the practical design and operation of power plants, chemical plants, pipeline transportation systems, and wells. All of these are components of the systems used to capture and store carbon dioxide (CCS). [..] Read more

Abstract: Household appliances often utilize polymer-metal bonding, typically achieved through adhesive bonding or press-fitting techniques. Corrosion resistance is a major factor in household appliances, as corrosion can compromise the functionality and aesthetics of household appliances. [..] 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“.

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).

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.

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: 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

Abstract: The production of iron in blast furnaces involves a number of entirely different processes such as: chemical, mechanical, and physical. The input materials often contain several negative elements, such as heavy metals. [..] Read more

Abstract: The content of the paper is a brief description of the basic characteristics of the reactive diffusion in the dissolution of solid copper in the melt of tin solder. Furthermore, it deals with the theory of growth kinetics of intermetallic phases during heat treatment, and a description of lead-free solders and related problems during soldering. [..] Read more

Abstract: Slags formed during pyrometallurgical extraction of zinc and lead contain numerous metals, and can provide a valuable source of these. Metal recovery from Zn-Pb slags can be accomplished using a pyrometallurgical method consisting in recovering materials at sufficiently high temperatures by transferring them to specific condensed phases (including metallic alloys) or the gas phase with subsequent condensation.

Abstract: 3D printing is a modern and widely used technology that has reached virtually all sectors of human activity, from the automotive industry to medical fields. Silver nanoparticles (AgNPs) have considerable industrial potential and are intensively studied regarding their antibacterial capability. [..] Read more

Abstract: This work summarizes results and progress in new method development for identification of material properties of steel. This work deals with application of the small punch test for evaluation of material degradation of power station in the Czech Republic within the project TE01020068 “Centre of research and experimental development of reliable energy production, work package 8: Research and development of new testing methods for evaluation of material properties”.

Abstract: Residual stresses exist in material independently of the presence of any external loads. Their presence may not be readily apparent and so they may be overlooked or ignored during a process of engineering design. [..] Read more
