Chemical compatibility between components in magnesium-carbon composites
Chemická kompatibilita zložiek v kompozitoch typu horčík-uhlík
Program: VEGA
Project leader: Mgr. Kúdela ml. Stanislav PhD.
Annotation:The present project is focused on the problem of the formation of reaction bond between the matrix and the reinforcement in magnesium - carbon fiber type composites. According to the project idea, the preform of carbon fibers will be infiltrated with magnesium alloy containing carbide-forming element X (Li, Si) wherein the extent of formation of carbides will be controlled through: (a) concentration of the element X, (b) graphitization degree of carbon fibers and (c) temperature-time regime of the infiltration process, in order to prepare the composites with powerful fiber/matrix interfacial bond. The main scientific goal of the project is to investigate impact of interaction between components on the deformation behavior of given composites and, on this basis, to optimize their fabrication process. The project is thematically divided into two stages: 1. Experiments of the pressure infiltration of the preform of various types of carbon fibers with Mg-X alloys in a laboratory autoclave at variable processing parameters (temperature, pressure, time) to prepare the composites of the given type. 2. Study of the relationship between the structure and the deformation behavior of composites prepared in order to characterize the functionality of the reaction bond. As a result, there should be proposed a suitable carbon fiber type, optimum composition of magnesium alloy and optimum processing parameters.

Project leader: Ing. Kováčik Jaroslav PhD.
Annotation:Scientific objective of the project is preparation and study of the properties, machinability and surface treatment of Ti-based composites with non reacted embedded phases. As embedded phase graphite, B4C, BN, TiN will be considered. The goal is to decrease the composite weight while improving some physical and mechanical properties of its surface, e.g., coefficient of friction, wear resistance and hardness. In addition to the preparation of composites, possibilities of machinability and surface treatment of Ti and prepared composites will be further explored using laser beam machining and electro-spark deposition. The research will focus on determining the amounts of qualitative/quantitative phases present in the composite/surface layer, their distribution and morphology depending on parameters of used technology.

Investigation of advanced materials suitable for highly effective heat storage
Štúdium progresívnych materiálov vhodných pre veľmi efektívne uskladňovanie tepla
Program: VEGA
Project leader: Ing. Jerz Jaroslav PhD.
Annotation:The project aims to investigation of the energy balance of the Phase Change Materials (PCMs) and composites with a matrix of these materials, which have good potential for applications in energy-efficient buildings in which the use of solar energy is the main strategy for heating and hot water preparation. Thermal characteristics of developed materials will be tested in conditions which enable not only efficient use of energy obtained at the time of its surplus in order to create a thermally comfortable indoor environment during the harsh winter, but also effectively dissipate heat from the interior during the extreme heat of summer and effective utilize this heat for water heating. Studied strategy of the accumulation of thermal energy in the interior of buildings using the heat capacity of construction of the building allows proper control of internal temperature changes, increase thermal comfort and thereby reduce the cost for hot water preparation, winter heating and summer keeping cool indoors.

Study of thermophysical properties of composites based on TiB2 and ZrB2 with copper matrix for high temperature applications
Štúdium termofyzikálnych vlastností kompozitov na báze TiB2 a ZrB2 s medenou matricou pre vyskoteplotné aplikácie
Program: VEGA
Project leader: Ing. Beronská Naďa PhD.
Annotation:The project is focused on the fundamental research of composite materials containing a ceramic phase (particles or preform) with extremely high melting temperature (TiB2 or ZrB2), wherein the matrix consists of a material with high thermal conductivity (copper, resp. Cu alloys). The composites will be prepared by gas pressure infiltration of molten metal into the ceramic preform of different porosity. One of the objectives of the project will be to determine which interactions between the components significantly influence the penetration of molten metal into the sample volume. As soon as the parameters of composites preparation are optimized the corresponding changes in the microstructure will be analyzed and thermophysical properties of the composite will be measured before and after thermal cycling at the temperature of 1000 °C. The findings will be used to prepare composites of simple and complex shapes with increased resistance to high temperatures and very good thermal and electrical conductivity.

On the bonding between native Al2O3 layers and the effect of intentionally entrapped gasses in forged Al powders.
Štúdium väzby medzi natívnymi Al2O3 obálkami a vplyvu zámerne uzatvorených plynov u výkovkov atomizovaných Al práškov
Program: VEGA
Project leader: Ing. Krížik Peter PhD.
Annotation:The aim of the project is study of phenomena in powder-metallurgical (PM) compacts prepared by quasi-isostatic forging of aluminium (Al) powders with minimal plastic deformation induced during consolidation. Such consolidation results in fine grain Al structure stabilized with continuous nanometric thick amorphous network of native oxide (am-Al2O3) characterised with enhanced high temperature properties and thermal stability of the material. The project aims to study systematically and describe the phenomena listed below, with major impact on performance of these compacts (with emphasis on the mechanical properties): - the conditions for formation of bonding between initial am-Al2O3 layers on the surfaces of Al powders, that later forms the continuous nanoscale thick network in compacts - description of the effect of gases intentionally entrapped and compressed in the compacts structure during consolidation (expected theoretical density of compacts is near to 100%) - the effect of thickness, morphology and crystal structure of Al2O3 layer on formation of continuous nanoscale thick network

Development of the methodology for preparation of ultrafine and fine grain materials based on Al and AlTi for microstructural characterization via EBSD method
Výskum metodík prípravy ultrajemných a jemnozrnných materiálov na báze Al a AlTi pre mikroštruktútnu charakterizáciu pomocou EBSD metódy
Program: VEGA
Project leader: Ing. Nosko Martin PhD.
Annotation:The role of EBSD (Electron BackScatter Diffraction) in microstructural characterization of materials continuously increases. However, besides the correctly adjusted system, the preparation of the analysed samples that differs from material to material plays a key role in this analysis. Previous studies were directed towards large grain materials based on Fe, Ti, NI Al etc. where the analysis provides satisfactory results. Completely different situation is in materials exhibiting large quantities of grain boundaries i.e. locations where the regularity of crystal lattices is interrupted. Here the actual limits of the EBSD methods are not set yet. The project is focused to study the key methods and parameters of sample preparation that are decisive in EBSD analysis of ultrafine and fine grained materials. The results will be tested on Al and AlTi based materials.

Výskum vzťahu pozdĺžnej nerovnosti vozovky a jazdného komfortu v motorovom vozidle
Program: VEGA
Project leader: Ing. Múčka Peter CSc.
Annotation:The project is aimed experimentally determine the relation between ride comfort on the driver seat in a motor vehicle and measured longitudinal road unevenness. Parameters of the measurement will be vehicle type, vehicle speed, road type and level of longitudinal unevenness. The aim is more accurately classify road unevenness using the measured response of vibration acceleration. Group of unique in situ measurements will be faced with different road classifications often based on simulated vibration response. Possibility of different road unevenness indicators to reflect ride comfort will be estimated. Relation between the parameters of road elevation power spectral density (unevenness index and waviness) and ride comfort will be estimated, which has not yet been published. Results could provide a contribution to an increase in ride comfort, ride safety and decision making on road maintenance.
