Opis:
The present study deals with the application of High Resolution Transmission Electron Microscopy (HRTEM) to dark layers, occurring in the speleothems of Domica Cave (Slovakia). Chemical pre-treatment was necessary for sample purification and the effective extraction of carbon soot. For purposes of comparison, soot aggregates obtained from laboratory experiments on the combustion of beech wood and collected from a diesel engine also were studied. HRTEM analyses of combustion products permit a distinction to be made between soot aggregates that originated in different combustion processes. The diameter of spherical, primary particles depends on the conditions of combustion, notably temperature. Burning in diesel engines produces soot with relatively small, primary particles (diameter dp = 34 ± 4 nm). Primary, spherical particles of soot aggregates, obtained from the combustion of beech wood, were larger (diameter dp = 42 ± 5 nm). The diameters of primary particles of soot separated from Domica flowstones (samples DOM1 and DOM2) were similar to the wood samples (dp = 50 ± 9 nm). Another type of carbonaceous particle, obtained in the combustion process, had a spherical shape, but the diameter of about 50–500 nm was significantly larger than that of soot. Analyses performed on two samples (DOM S1 and DOM S2) confirmed that the black laminae owed their colour to particles, formed during wood combustion and later retained in the speleothems.

Opis:
The aim of presented paper is an investigation of the structure changes in AlSi9Cu alloy after remelting by a laser beam. Scanning transmission electron microscopy was applied for structure characterization and precipitates phase identification. In the raw material, precipitates were larger and during remelting such precipitates were dissolved and very fast crystallization came next. Observed precipitates are generally uniform: in size, shape, and chemical composition. Generally, after remelting precipitates are not uniformly distributed in the whole sample but areas with dense, nanometric precipitates are common. Numerous volumes with elongated Ti precipitates, identified as Ti(Al_{1-x}Si_{x})₃, were found. Observed precipitate can strongly affect material properties (even in a case of law Ti concentration) because it may act as a crystal nucleus for other phases.

Opis:
Two catalysts, nickel and cobalt, supported on MgO were used for carbon nanomaterials deposition by CO disproportionation. The syntheses were performed at 795 and 900 K in the hydrogen atmosphere. The resulting products were investigated using atomic force microscopy, scanning electron microscopy, and high-resolution transmission electron microscopy. Although in the literature carbon nanofibres are expected to form in the hydrogen presence, we obtained carbon nanotubes, which were multiwall and twisted with the outer diameter of 10-120 nm and the tube length up to 10 μm.

Opis:
Aluminium recycling is cost-effective and beneficial for the environment. It is expected that this trend will continue in the future, and even will steadily increase. The consequence of the use of recycled materials is variable and difficult to predict chemical composition. This causes a significant reduction in the production process, since the properties of produced alloy are determined by the inicrostructure and the presence of precipitates of other phases. For this reason, the type and order of formation of precipitates were systematically investigated in recent decades. These studies involved, however, only the main systems (Al-Cu. Al-Mg-Si, Al-Cu-Mg, Al-Mg-Si-Cu), while more complex systems were not analysed. Even trace amounts of additional elements can significantly affect the alloy inicrostructure and composition of precipitates formed. This fact is particularly important in the case of new technologies such as laser surface treatment. As a result of extremely high temperature and temperature changes after the laser remelting large amount of precipitates are observed. Precipitates are nanometric in size and have different morphology and chemical composition. A full understanding of the processes that occur during the laser remelting requires their precise but also time effectively phase identification, which due to the diversity and nanometric size, is a major research challenge. This work presents the methodology of identification of nanometer phase precipitates in the alloy AlSi9Cu, based on the simultaneous TEM imaging and chemical composition analysis using the dispersion spectroscopy using the characteristic X-ray. Verification is performed by comparing the simulation unit cell of the identified phase with the experimental high-resolution image.

Opis:
The feasibility of effluent treatment in separate processes and in integrated systems has been compared. In the sorption process, carbon nanotubes were used in a pressure installation, enabling execution of the process of sorption with nanofiltration in a cross-flow system. Evaluation of treatment effects based on the measurement of typical pollution parameters (COD, TOC, phenolic index, forms of nitrogen and phosphorus) and concentration of bisphenol A. The results show poor feasibility of sorption as a process for advanced treatment of municipal effluent. Effluent polishing in integrated sorption-nanofiltration systems, however, guaranteed high removal rates of organic and inorganic pollutants.

Opis:
The aim of this article of this paper is to present issues related to characterization of nanometric-sized carbides, nitrides and/or carbonitrides formed during tempering of carbide-steel cermets. Closer examination of those materials is important because of hardness growth of carbide-steel cermet after tempering. The results obtained during research show that the upswing of hardness is significantly higher than for high-speed steels. Another interesting fact is the displacement of secondary hardness effect observed for this material to a higher tempering temperature range. Determined influence of the atmosphere in the sintering process on precipitations formed during tempering of carbide-steel cermets. So far examination of carbidesteel cermet produced by powder injection moulding was carried out mainly in the scanning electron microscope. A proper description of nanosized particles is both important and difficult as achievements of nanoscience and nanotechnology confirm the significant influence of nanocrystalline particles on material properties even if its mass fraction is undetectable by standard methods. The following research studies have been carried out using transmission electron microscopy, mainly selected area electron diffraction and energy dispersive spectroscopy. The obtained results and computer simulations comparison were made.

Opis:
The aim of this work is to determine the effect of manufacturing conditions, especially milling time, on the microstructure and crystallite size of a newly developed nanostructural composite material with the aluminium alloy matrix reinforced with halloysite nanotubes. Halloysite, being a clayey mineral of volcanic origin, is characterized by high porosity and large specific surface area. Thus it can be used as an alternative reinforcement in metal matrix composite materials. In order to obtain this goal, composite powders with fine microstructures were fabricated using high-energy mechanical alloying, cold compacting and hot extrusion techniques. The obtained composite powders of aluminium alloy reinforced with 5, 10 and 15 wt% of halloysite nanotubes were characterized with SEM, TEM and XRD analysis. It has been proven that the use of mechanical alloying leads to a high degree of deformation, which, coupled with a decreased grain size below 100 nm and the dispersion of the refined reinforcing particles–reinforces the material very well.
Celem niniejszej pracy było określenie wpływu warunków wytwarzania, w szczególności czasu mielenia, na strukturę i wielkość krystalitów nowo opracowanych nanostrukturalnych materiałów kompozytowych o osnowie stopów aluminium wzmacnianych nanorurkami haloizytowymi. Haloizyt, będący minerałem ilastym pochodzenia wulkanicznego, charakteryzuje się dużą porowatością, dużą powierzchnią właściwą, i może stanowić alternatywne wzmocnienie metalowych materiałów kompozytowych. W tym celu przy użyciu wysokoenergetycznego mechanicznego stopowania w młynie kulowym wytworzono rozdrobnione i trwale połączone proszki kompozytowe, które następnie poddano zagęszczaniu na zimno i wyciskaniu na gorąco. Tak opracowane materiały kompozytowe o udziale masowym haloizytowego wzmocnienia 5, 10, 15% zbadano metodami skaningowej i transmisyjnej mikroskopii elektronowej oraz rentgenowskiej analizy fazowej. Stwierdzono, że wywołane mechanicznym stopowaniem silne odkształcenie plastyczne i zmniejszenie rozmiaru ziarna poniżej 100 nm oraz dyspersja haloizytowych cząstek wzmacniających wpłynęła na znaczne umocnienie materiałów kompozytowych.

The addition of hard ceramic particles of nc-(Ti, Mo)C in carbon network into Ti matrix has been proved to be an efficient way to enhance their properties. The purpose of this work was to analyze the corrosion, tribological, mechanical and morphological effects of combining nc-(Ti, Mo)C/C with titanium metal, to create a unique composite via selective laser melting technique (SLM). Composites with different weight percentage (5, 10 and 20 wt%) of ceramic phase were produced. The samples of pure Ti and Ti-6Al-4V alloy were also tested, as a reference. These composites were examined for corrosion resistance in body fluid (artificial saliva solution). Moreover, the properties of titanium composites reinforced with nc-TiC powders were compared. It was stated that mechanical properties were significantly improved with increasing amount of nc-(Ti, Mo)C/C in Ti matrix. In terms of corrosion resistance, the composites showed worse properties compared to pure titanium and Ti-6Al-4V alloy, but better than TiC-reinforced composites.

Opis:
The paper presents the issue of synthetic cast iron production in the electric induction furnace exclusively on the steel scrap base. Silicon carbide and synthetic graphite were used as carburizers. The carburizers were introduced with solid charge or added on the liquid metal surface. The chemical analysis of the produced cast iron, the carburization efficiency and microstructure features were presented in the paper. It was stated that ferrosilicon can be replaced by silicon carbide during the synthetic cast iron melting process. However, due to its chemical composition (30% C and 70% Si) which causes significant silicon content in iron increase, the carbon deficit can be partly compensated by the carburizer introduction. Moreover it was shown that the best carbon and silicon assimilation rate is obtained where the silicon carbide is being introduced together with solid charge. When it is thrown onto liquid alloy surface the efficiency of the process is almost two times less and the melting process lasts dozen minutes long. The microstructure of the cast iron produced with the silicon carbide shows more bulky graphite flakes than inside the microstructure of cast iron produced on the pig iron base.

Influence of the repetitive corrugation on the mechanism occuring during plastic Deformation of CuSn6 alloy This paper presents the research results of Cu$n6 alloy strip at semi-hard state, plastically deformed in the process of repetitive corrugation. The influence of process parameters on the mechanical properties and structure of examined alloy were investigated. Examination in high-resolution transmission electron microscopy (HRTEM) confirmed the impact of the repetitive corrugation to obtain the nano-scale structures. It has been found, that the application of repetitive corrugation increases the tensile strength (Rm). yield strength (Rpo:) and elastic limit (Rpo.os) of CuSn6 alloy strips. In the present work it has been confirmed that the repetitive corrugation process is a more efficient method for structure and mechanical properties modification of commercial CuSn6 alloy strip (serni-hard) as compared with the classic rolling process.

Opis:
In this paper there are presented results of high resolution transmission electron microscope investigation concerning the structure of the Zn-Al-Si cast zinc alloy with Sr addition for crystal structure refinement after thermo-derivative analysis performed using the universal metallurgical simulator and analyzer platform. The thermo-derivative analysis allows to determine the specific points of the solidifying alloy, which is helpful for phase determination and proper heat treatment condition determination, allowing to reduce the energy costs and obtaining higher mechanical and functional properties. Using transmission electron microscopy, especially selected area diffraction method appliance it was possible to determine the phases occurring in the alloy in the state after chemical composition modification as well as after appliance of very precisely controlled cooling rate. The morphology and size of the microstructure of micro-sized eutectic was possible to determine as well the lattice parameters of the Zn α -phase. Particularly the overview will be also directed on the high resolution transmission electron microscope to achieve good insight into the structural changes on the atomic scale.

In presented work we report results of simple and viable method for producing Au/CNT composites. Chemical composition and crystallographic structure of the Au/CNT composites was confirmed by X-ray diffraction measurements, while transmission and scanning electron microscopy were used to characterize the morphology of nanocrystals as well as the distribution of nanocrystals in the composite. The obtained particles with relatively small diameter (less than 9 nm) were found to be spatially well dispersed on the carbon nanotubes. The density of attached Au-nanoparticles is not sufficient, and cannot be improved by simple increasing gold loading.
