Syntesis and characterization of novel organic-inorganic polymeric hybrids for 3D printing
Príprava a charakterizácia pokročilých anorganicko-organických polymérnych hybridov pre 3D tlač
Program: Medziakademická dohoda (MAD)
Project leader: Ing. Bureš Radovan CSc.
Annotation:Three-dimensional printing is currently largely bound to the use of polymer materials supplied by the printer manufacturer. This, however, greatly limits the wider application of 3D printing of objects with specific physicochemical and mechanical properties. The primary reason of this limitation is the requirement for biocompatibility, biodegradability, enhancement of anti-corrosion properties, or specific requirements for the mechanical and electrical properties of the resulting products. Consequently, the objective of this project is the synthesis and characterization of novel advanced polymer composites with inorganic fillers applicable in 3D printing. The aim will be to examine the influence of the size and shape distribution of inorganic fillers on the structure and physicochemical properties of the newly formulated composites. Increased attention will be paid to modifying the macromolecular structure and microstructure at the interface between the organic and inorganic phases and unveiling the induced changes in the macroscopic properties of the infiltrated hybrid materials.

Progresívne metódy úpravy funkčných a mechanických vlastností práškových materiálov
Program: Medziakademická dohoda (MAD)
Project leader: RNDr. Kovaľ Vladimír PhD.
Annotation:Rapidly solidified powder alloys as well as mechanically prepared powder metal alloys have a limited plastic deformation capability. Limited plasticity of the powders leads to their limited form-ability and in some cases prevents compacting of the powder by uniaxial cold pressing. Structural defects typical for mechanically synthesized alloys also cause deterioration of their electrical and magnetic properties. The aim of the project is to investigate the progressive processing methods of mechanically prepared powder alloys in order to improve their compaction, while maintaining or improving their electrical, magnetic and mechanical properties. The project solution can bring original findings, leading to expansion of the usability of fast-solidified and mechanically synthesized alloy powder materials in industry.

Program: VEGA
Project leader: Ing. Falat Ladislav PhD.
Annotation:The project intention is to investigate the effect of intermetallic Laves phase in thermally exposed 9Cr creep-resistant steels on degradation of their mechanical and brittle-fracture properties. Microstructure evolution aimed at kinetics of precipitation and coarsening of Laves phase will be studied in dependence of the conditions of initial heat treatment. Apart from comparison of the properties of long-term thermally exposed states (i.e. with presence of Laves phase) with the properties of initial material states without long-term thermal exposition (i.e. without Laves phase), the key task will be the study of the effect of supplemental heat treatment of thermally-exposed states (without notable effect on Laves phase precipitation/coarsening) on potential modification of the properties of creep-resistant steels. The main aim of the project is to re-evaluate and eventually complete up-to now generally accepted opinion on the Laves phase considered as the main embrittling factor in creep-resistant steels.

Program: VEGA
Project leader: RNDr. Kováč František CSc.
Annotation:The project is a goal-oriented on the development of isotropic electrical steels with high induction. The idea of the project is based on the increase of cubic texture intensity and the control of the Goss texture component in the sheet plane. The mentioned crystallographic texture will be achieved by columnar grains growth via the mechanisms of diffusion-controlled and deformation-induced grain boundary motion. The intensity of the cubic texture component will be increased from sub-surface region to the central part. At the same time the high intensity of the deformation component (111) [0vw] will be eliminated at the middle part of steel. Such a microstructural and textural state will be the basis for the isotropy of magnetic properties at a relatively low losses and a high isotropy of magnetic induction. The output of the project will be not only the acquired knowledge in field of basic research, also will be proposed a technological process for the preparation of such a microstructure.

Effect of continual and pulsating fluid jet on microstructure, properties and integrity on materials
Vplyv kontinuálneho a pulzujúceho kvapalinového prúdu na mikroštruktúru, vlastnosti a integritu v materiáloch.
Program: VEGA
Project leader: RNDr. Hvizdoš Pavol CSc.
Annotation:The project is focused on the experimental observation and assessment of the interaction of continuous and pulsating liquid jet with and pulsating water jet with frequency of 20 kHz with material. The energy of the water stream at the site of action releases the mass and causes elastic or plastic deformation, thereby initiating dynamic physical phenomena. These phenomena are manifested in the form of periodic, continuous but non-homogeneous manifestations of vibrational and acoustic emission and their subsequent dynamic manifestations in a wide frequency spectrum. The ongoing disintegration process deforms the wave - changing its shape. An analysis of the waveform change can be identified in the elastic and plastic regions. Through the dynamic signal timing, the process of interaction of the water stream with the material can be controlled, resulting in improved mechanical resistance of the surface layer, controlled change of the microstructure, elimination of delamination and residual stresses.

Vývoj vysoko-legovaných izotrópnych elektro ocelí pre trakčné motory elektromobilov
Program: APVV
Project leader: RNDr. Kováč František CSc.
Annotation:In this project, for the production of high strength electrical steel type “finish”, we aim to propose an original concept of chemical composition and microstructural design with the desirable crystallographic texture which would be provided a combination of excellent electro-magnetic and high strength properties. The strength properties will be provided by high alloying of steels which are based on substituents elements with Si content from 3 to 3,5 wt.%, Al content from 0,5 to 1,5 wt.%, Cu content up to 0,5 wt.%, and P content up 0,10 wt.%. The low value of watt losses and high level of magnetic induction will be achieved by means of coarse-grained columnar or coarse-grained equiaxial microstructure with average grain size in the range from 150 to 300μm and with increased intensity of cube and Goss texture components at the expense of deformation texture. The evolution of the final microstructure will be based on the use of the strain-induced growth of ferrite grains through the thickness of the sheet from its surface to the central part. At the same time, we want to eliminate the liability to the brittle failure of materials during the cold rolling. It will be realised by optimization of previous thermal deformation exposures in the hot rolling process as well as optimization of deformation process of cold rolling with "tailor-made" parameters of rolled steel.The development steel will be used in traction engines of electric vehicles and in high-speed electric motors with high requirement for the power.

Annotation:Nowadays, there is a characteristic continual pressure on the emission reduction produced by the cars. One possible way to reduce the amount of emissions produced by the automobiles is the reduction of the body weight. The weight of the automobile could be reduced through the hybrid car body, which consists of different materials based on the light alloys, composite materials and high-strength steel sheets. Solutions related to such hybrid car body designs must be addressed in to the forming, but also to the joining of the individual parts of such multi-material conception. The aim of the project is the optimization of the forming conditions of aluminium alloy sheets and high-strength steel sheets to increase the process efficiency. The appropriate joining technique will be proposed based on the results of the analyses of the stress-strain states of the formed parts. A comparison of strength and load-bearing capacity of the joints after different intensity of deformation and stressstrain states will be the assumed result. Effective and innovative methods of joining of aluminium and highstrength steel sheets after different intensity of deformation and stress-strain states will be assessed. The results obtained from the optimization of the joining process of the materials made of ferrous and non-ferrous metals will allow the strength of joints to be increased.
