Abstract: Report deals with the occurrence of copper and copper oxides in the Heating Plant heat-transfer circuit, particularly in the steam-water system of high pressure steam boilers. Boilers produce high-pressure superheated steam, which is used for cogeneration of heat and electricity. [..] Read more

Abstract: When dealing with corroded objects, it is necessary to identify the corrosion products to develop a proper treatment for this particular object. Using X-ray diffraction is still suitable to do the phase composition analysis of the material; however it does the analysis of the material in bulk. [..] Read more

Abstract: Possibilities of the use of alternative drives from the point of view of operation of an industrial enterprise are at present almost unlimited, and it will always depend on concrete conditions of the company to which measure the company will decide to use alternative fuels in its fleet. One of the main arguments for using of alternative motor fuels are ecological reasons. [..] Read more

Abstract: The paper describes combination of optical and electronic methods together with IR analysis for evaluation of the paint coatings. Based on these methods the fingerprint of each paint layers is identified according to requirements of ISO 12944-9. [..] Read more

Abstract: The aim of this study was to evaluate the possibility of the metallurgical wastes (slags and fly ash) utilization as a support for photocatalyticaly active composites. Metallurgical slags (MS) represent large volume group of by-products originated during the metallurgical production processes. [..] Read more

Abstract: Suitable molecular or biochemical markers are sought for rapid diagnostics of cancer. A very promising candidate is the sarcosine (SAR) amino acid, which is elevated in the urine of the patients with prostate cancer. [..] Read more

Abstract: Nanofibrous matrices represent an attractive material for biomedical applications – mainly due to their high specific surface and small pore size, which make them interesting material for drug delivery matrixes construction. Besides the morphological characteristics, the surface functionality strongly affects the drug-matrix interaction, drug conjugation and drug release kinetics. [..] Read more

Abstract: The paper describes the mechanism of destruction of forging die used for plastic working processes by die forging on hammers. The test material was a matrix after exploitation for plastic processing using the hot forging method, made of WNLV grade material. [..] Read more

Abstract: The aim of this work is to develop and test a new method for identification of material properties of the steel. This work deals with application of the small punch test for evaluation of material degradation of power station in the ČEZ company (main Czech energetic company) 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”. [..] Read more

Abstract: The intended operation time prolongation of the key components of fossil-fuelled power plants working in the creep conditions over 200,000 or even 250,000 hours (far beyond their original design lifetime) must be accompanied by thorough and extensive monitoring of the current material state and particularly creep damage. The extent of cavitation damage is routinely tested in-situ by using replica method and its quantification is based on a practice stated in VGB-TW 507, NORDTEST NT TR 170 or NORDTEST NT TR 302 that further develop the original Neubauer's classification.

Abstract: It is more and more difficult for companies and firms to survive in the highly competitive environment at the present. This is why they try to find ways to achieve competitive advantages, which is associated with investments in innovative technologies or information technologies. [..] Read more

Abstract: The paper deals with a comparative analysis of reducibility of metallurgical sinter typical with high and low basicity. The samples were performed at 950°C of reduction test according to ISO 4695 which characterized their reducibility potential in CO atmosphere. [..] Read more

Abstract: Coke is one of the basic energy sources in the blast furnace process. Its quality essentially then determines the course of the blast furnace process. [..] Read more

Abstract: One bi-layer Ni-Ti thin films with chemical compositions of Ni45TiCu5/Ni50.8Ti (numbers indicate at.%) determined by energy dispersive X-ray spectroscopy was deposited on Si substrates using RF magnetron sputtering. The structures and transformation temperatures of annealed thin films at 773 K for 1 h were studied using grazing incidence X-ray diffraction (GIXRD) and differential scanning calorimetry (DSC), respectively. [..] Read more

Abstract: Stable process can be called a process in which variability is the result of many accidental causes, resulting in minor changes, not a specified number of reasons, resulting in significant changes in the parameter values. In the article the map of process stability, which is a result of process stability (X axis) and product quality (Y axis), was used. [..] Read more

Abstract: Nowadays one of the most important global issues in the heavy industry and specially in metallurgical sector is the allocation of carbon dioxide emission allowances. The equity in allocation of emission allowances is discussed offend with this problematic. [..] Read more

Abstract: An intensive population growth, progressing social and economic development processes and growing urbanization of rapidly developing countries significantly translate into an increase in the amount of generated waste. At present, approx. [..] Read more

Abstract: The electromagnetic properties of strips made of grain-oriented electrical steels (GOES) are strongly affected by the sharpness of the Goss texture. The Goss texture is defined by {110} 001, where the planes {110} are parallel to the surface of the strip and the directions 001 are parallel to the rolling direction. [..] Read more

Abstract: In the area of supply chain management, selecting the right suppliers plays a key role in ensuring the smooth operation of the entire process. Traditional evaluation methods of the suppliers often rely on clear-cut metrics, failing to consider the complexity and uncertainty that often accompany these processes. [..] Read more

Abstract: The boronizing is a thermochemical process in which the boron atoms are introduced into the steel surfaces. This study evaluates the fracture toughness of boride layers developed by powder boronizing of high-chromium steels Sleipner, K 190, Royalloy, Sverker 21 and Sverker 3. [..] Read more
