Program:	Bilateral – other
Project leader:	Mgr. Petryshynets Ivan, PhD.
Annotation:	The main task of the project is to investigate the effect of laser hardening in combination with deep cryogenic treatment on fracture toughness, wear resistance and load – carrying capacity of subsurface region of cold work tool steel and to analyze the modification of microstructural parameters depending on the tool steel type and chemical composition. The experimental materials will be created with three groups of tool steels which are determined for the cold work. The first group will consist of carbon steel with carbon content up to 0.7 wt%, the second groups will be low-alloy steels, and the third group will be the medium alloy steels. These materials will be treated by recommended conventional heat procedures. Subsequently, the materials will be subjected to the treatment by laser beam in order to melting the surface or heating the surface to the selected temperature of austenite as a function of technological parameters of laser hardening and to deep cryogenic treatment in order to remove residual stresses, achieve the transformation of retained austenite and modify the dislocation structure and carbon distribution in the martensitic solid solution. For each material variations, optimal parameters of laser and cryogenic treatments will be defined in order to improve the main mechanical properties of investigated tool steel.

These materials are attractive research objects and possess combinations of physical properties which are important for practical applications and fundamental research. Lithium tetraborate (Li2B4O7) is a promising non-linear material for frequency conversion including the generation of the fourth and fifth harmonics of the Nd:YAG laser. The lithium potassium borate (LiKB4O7) single crystal is new promising material for application in non-linear optical and acousto-optic devices. It could be implemented in solid-state laser systems for various practical applications. Moreover, lithium borate crystals find applications in thermoluminescence dosimetry of fast neutrons and in neutron-imaging cryogenic detectors. Borate glasses are of great interest because of their good ionic conductance properties and potential application in solid state batteries. Other applications of lithium tetraborate include surface and bulk acoustic wave devices, pagers, cordless and cellular telephones, and data communication devices.

MAMINA – Macro, Micro and Nano Aspects of Machining
Makro, Mikro a nano aspekty obrábania
Program:	FP7
Project leader:	doc. Ing. Saksl Karel, DrSc.
Annotation:	The use of titanium, nickel-base and cobalt-base alloys is necessary for production of turbine parts and other components by the aerospace and power generation industries due to their high strength even in high-temperature regimes. On the other hand, these materials are known as themost difficult-to-machine metallic materials and, so far, only small progress has been made to improve their machinability. During the production of turbine components up to 50% of themanufacturing costs can be related to machining. Hence, the reduction of the production costs bythe optimisation of the cutting process is mandatory for European manufacturers to remaininternationally competitive.The MAMINA project will combine the work of ninenteen European universities, researchinstitutions and industrial companies to analyse and improve the machinability of three selectedalloys that are widely used in industry, namely Ti15V3Cr3Al3Sn (a titanium-base beta-alloy),Inconel IN706 (a nickel-base superalloy) and X40 (a cobalt-base alloy). As the chip formation isone of the key factors influencing the machinability of these materials, this process will be studiedin detail in a multidisciplinary approach. 24 early stage researchers from the fields of theoreticalphysics, materials science and mechanical engineering will work under the supervision ofexperienced scientists on metal cutting experiments, material analyses and simulations at the macro,micro- and nano-scale.Three different approaches will be made to improve the cutting process of the investigated alloysby means of: (1) introduction of enhanced manufacturing techniques; (2) production of progressivetools with extended endurance, and (3) development of free-machining alloys by the use ofpermanent and temporary alloying elements. The results will be transferred to applications by theindustrial partners of the consortium. It is expected that the production costs of improved machining will be reduced by up to 20%

HydroHEA – Research and development of new high – entropy alloys for efficient hydrogen storage in energy applications
Výskum a vývoj nových vysokoentropických zliatin určených na efektívne uskladnenie vodíka v energetických aplikáciách
Program:	SRDA
Project leader:	doc. Ing. Saksl Karel, DrSc.
Annotation:	The presented project aims to development and research of metal hydride materials of the latest generation – highentropyalloys, which report the highest volumetric storage capacity of hydrogen among all materials used so far.We intend to utilize these materials in metal hydride tanks of hydrogen compressors, which are being developed inSlovakia by the project cooperating organisation – FME TUKE.In June 2020, the European Commission presented the Union\’s hydrogen strategy, which states that hydrogen andthe hydrogen economy are among the key technologies for the future of industry in the EU.The presented project aims to meet the goal of efficient and safe hydrogen storage. Up to date studies show thehighest volumetric hydrogen storage capacity of 150 kg/m3, out of all conventional alloys, is reached by Mg2FeH6metal hydride. In 2016, Sahlberg et al. in a publication entitled "Superior hydrogen storage in high entropy alloys"confirmed that the high-entropy alloy TiVZrNbHf can store an incredible "superior" of 210 kg/m3 of hydrogen in itsstructure with a ratio of hydrogen atoms to metal (H / M) 2.5. However, the problem of the alloy is its relatively high density of 7.81 g/cm3, which makes it too high for transport applications. In the project, we will design, prepare andfully characterize a series of completely new high-entropy materials with a low density <7 g/cm3. Materials thatmeet the targets of absorption capacity (> 2 wt% and> 220 kg H2/m3), low desorption temperature (<140C) andhigh cyclic absorption / desorption stability (> 1000 cycles with capacity drop of less than 10%) we will patent. Thealloys will also be tested in a hydrogen compressor, which will undoubtedly contribute to the further evaluation ofthe outputs of this project. In the project we will use our long-term knowledge and expertise in the design,preparation and characterization of high-entropy alloys.

BiAll-2 – Development of new bioresorbable alloys for intracorporeal implants
Vývoj nových bioresorbovateľných zliatin pre vnútrotelové implantáty
Program:	SRDA
Project leader:	Ing. Molčanová Zuzana, PhD.
Annotation:	The main goal of submitted project is to develop the new bioresorbable alloys Ca-Mg-Zn-NN and Ca-Mg-Sr-NNwith controlled rate of biodegradation (NN are solid solution strengthening and stabilizing elements). Developed alloys will be preferentially dedicated to fabrication of intracorporal implants for bone tissue engineering field. Members of project research team are highly focused on the investigation of these alloys systems since 2014. Essential and logical continuity of research activities are moving towards to experimental outputs into medical practice. However, this requires a large-scale investments of research capabilities to enhance the plastic deformability of alloys, while maintain their excellent strength properties and slow dissolution rate. Taking into account that healing of traumatic injuries needs different time of implant mechanical support, the great ambition of the project is to prepare alloys with possibility of controlling their dissolution rate. Another research point with hugepotential of success is handling and mastering of 3D printing of well -defined intracorporal implants from proposed alloys. One of the final research tasks will be in-vivo testing of implants dissolution in the environment of animals bone tissue and continuous monitoring of their degredation rate. Several state-of-the-art experimental techniques, such as HR-TEM microscopy or experiments using synchrotron and neutron diffraction techniques, will be used to study the atomic structure and microstructure of materials to meet the project objectives. Modern techniques of selective laser sintering and/or melting will be used for the production of final implants. The achieved outputs of the project research programme will be adapted by contracted private company Biomedical Engineering s.r.o. and displayed into clinical practice.

THERMAGS – Thermoelectric material Ag2S as green converter of heat from human body into electricity
Termoelektrický materiál Ag2S ako ekologický konvektor tepla ľudského tela na elektrinu
Program:	SRDA
Project leader:	doc. Ing. Saksl Karel, DrSc.
Annotation:	A carbon neutral society demands the development of efficient and energy saving technologies. Efficient thermoelectric devices have great potential to convert the waste heat from power plants, automotive engines, andindustrial processes into fruitful electricity. Another natural source of heat is our body. As the heat released by the human body is given for “free” wearable renewable energy generators (or harvesters) have potential to trigger revolution in the electronics industry in 21st century. For example, bendable, scalable, portable, and lightweight thermoelectrics can in future sourced flexible displays, medical image sensors, smart wearables, and large-area epapers to name a few. To date, state-of-the-art thermoelectrics is based on inorganic semiconductors that afford high electron mobility but lack in mechanical flexibility. By contrast, organic materials are amply flexible but low in electrical mobility and power output; the inorganic-organic hybrid design is a viable material-level option but has critical device-level issues for practical application. In flexible full-inorganic devices made of such Ag2S-based materials, high electrical mobility yielded a normalized maximum power density up to 0.08 W•m-1 near room temperature under a temperature difference of 20 K, orders of magnitude higher than organic devices and organic-inorganic hybrid devices. These results promised an emerging paradigm and market of wearable thermoelectrics.

Program:	VEGA
Project leader:	RNDr. Homolová Viera, PhD.
Annotation:	The project focuses on the study of phases, phase equilibria and phase diagrams in systems forhigh-temperature applications. The aim is to refine the uncertainty of phase diagrams and investigate unknownparts of selected binary systems by experimental methods of differential thermal analysis, X-ray diffraction andelectron microscopy and then to model their phase diagrams and thermodynamic properties using thesemi-empirical Calphad-method. The subject of the study are binary systems with iridium. Iridium is an elementwhich, due to its thermodynamic properties, is very interesting for use in the aerospace industry and due to itshigh corrosion resistance even at very high temperatures, it may potentially be suitable for use as part of gasturbine materials. The results of the project will allow to extend the possibility of designing new materials forhigh-temperature use by computational methods without the need for time-consuming experimental testing.

Histes – Development of high-alloy isotropic electrical steels for traction engines of electric vehicles
Vývoj vysoko-legovaných izotrópnych elektro ocelí pre trakčné motory elektromobilov
Program:	SRDA
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 beprovided 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.%, Alcontent 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 itssurface 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 rollingprocess 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 withhigh requirement for the power.

Re-evaluation of the effect of intermetallic phase on embrittling processes of creep-resistant steels
Prehodnotenie vplyvu intermetalickej fázy na procesy krehnutia žiarupevných ocelí
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 conditionsof 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.

Double-oriented electrical steels with high and isotropic magnetic induction.
Textúrne dvojito orientované elektrotechnické ocele s vysokou, izotrópnou indukciou.
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 theproject is based on the increase of cubic texture intensity and the control of the Goss texture component in thesheet plane. The mentioned crystallographic texture will be achieved by columnar grains growth via themechanisms of diffusion-controlled and deformation-induced grain boundary motion. The intensity of the cubictexture component will be increased from sub-surface region to the central part. At the same time the highintensity of the deformation component (111) [0vw] will be eliminated at the middle part of steel. Such amicrostructural and textural state will be the basis for the isotropy of magnetic properties at a relatively low lossesand a high isotropy of magnetic induction. The output of the project will be not only the acquired knowledge infield of basic research, also will be proposed a technological process for the preparation of such a microstructure.

Project leader:	Ing. Ballóková Beáta, PhD.
Annotation:	In response to the situation resulting from the spread of the SARS-CoV-2 virus, the research and development performed at workplaces of the Faculty of Mechanical Engineering of the Technical University of Kosice has been partially transformed into research and development of special respirators and filtration materials. The submitted project is focussed on the development and construction of respirators with separable filters without exhalation valves which provide efficient protection against SARS-CoV-2 virus. The aim of the project is the investigation, development and production of respirators with separable filters and the testing of novel filtration materials. Designing and production of the respirator will be carried out while applying biomimetic and ergonomic principles and modern additive manufacturing technologies, and the production of multicomponent filters will be carried out while applying a combination of powder metallurgy technology and electrospinning which will facilitate combining metal filters and polymer nanofibres. Also, ceramic components produced by 3D printing will be used as a protective packaging of the used nanofibres and nanoparticles. In order to achieve the project objectives, it will be necessary to carry out the fundamental investigation of filtration efficiencies of the suggested materials with virucidal effects based on copper and ions of silver of zinc. The purpose of the project is to develop and construct testing systems intended for identification of resistance coefficients of newly developed filtration materials, filter permeability using a suitable aerosol, as well as mask penetration through the facepiece contact line. Optimisation of the shape of the respirator facepiece will be based on the analysis of biological parameters of at least 20 human facial scans; this will facilitate elimination of potential infection by particles escaping through the space around the mask.

Within the project we plan to do also very ambitious experiments on X-ray free electron laser aiming to study dynamics of the solid state systems sampled in femtosecond timescales by X-ray photon correlation spectroscopy. Goals of this project are highly ambitious but achiavable will require application of the most sophisticated methods applied today in material research. The previous experiences of the research team proved by more than 70 scientific papers published in most prestigious scientific journals like Nature Physics, Physical Review Letters, Applied Physics Letters etc. we believe guarantees their fulfilment.

Annotation:	The project is focused on characterization of nano-scale precipitates and grain boundary segregdation of carbon in non-oriented electrical steel (NO ES) and development of an empirical model for assessment of relation between their morphology and core loss. Two groups of main objectives will be investigated by joint efforts of the Slovak and Slovenian groups. First, since magnetic properties of NO ES is very dependent on second phase particles (precipitates). Precipitates can have negative effects because they limit the grain growth during the final annealing and the direct negative effect is pinning of domain wall movements. The aim of the project therefore is to investigate the (nano)structures of NO ES in order to characterize the non-metallic inclusions and precipitate populations in ferrite matrix and determine the size, morphology, quantity and distribution. Purpose of the project is to produce a model for assessment of relation between size and morphology of the inclusions and (nano)precipitates and core loss.The second group of objectives consists in the studies of segregations of carbon on grain boundaries. A quite important role plays a carbon segragation at interfaces in the NO ES. This solute elemnt has an enormous effect on grain boundary migration and even very small ammount of concentration may significantly affects the recrystallization or grain growth phenomenta taking place in the NO steel during its heat treatment. However the knowladge of whow and whther indeed the carbon influence the grain boundary migration, even at small concentrations, in steel is still radumentary. This draws a need to sudy more deeply the presnce of carbon, even at small concentrations, in NO ES.Hence, the prospective results could lead to significant improvement in microstructure and texture control which have a direct affect on electromagnetic properties of NO ES.
