Research is focused on the clarification of densification mechanism in powder soft magnetic materials. Mechanical and magnetic properties of compacted materials will be correlated with parameters of compaction technology.

Syntesis and characterization of novel organic-inorganic polymeric hybrids for 3D printing
Príprava a charakterizácia pokročilých anorganicko-organických polymérnych hybridov pre 3D tlač
Program: Inter-academic agreement
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.

Progressisve methods for treatment of the functional and mechanical properties of powder materials
Progresívne metódy úpravy funkčných a mechanických vlastností práškových materiálov
Program: Inter-academic agreement
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.

Development of novel multifunctional materials for next generation magnetoelectric sensors and data storage devices
Vývoj nových multifunkčných materiálov pre magnetoelektrické senzory a úložiska digitálnych dát budúcej generácie
Program: Bilateral - other
Project leader: RNDr. Kovaľ Vladimír PhD.
Annotation:The main goal of the proposed project is to establish and develop a scientific cooperation between Slovakia and China in the field of multifunctional materials for advanced applications in microelectronics and spintronics. Joining of the research teams from both countries is motivated not only because of great technological potential of multifunctional materials but also due to the fascinating physics behind their unique properties. Multiferroics, exhibiting simultaneously ferroelectric and magnetic properties, are among the most attractive multifunctional materials. They allow for controlling the magnetic state of multifunctional devices with an external electric field, and vice versa. The main obstacle is, however, the scarcity of multifunctional magnetoelectrics in nature. Currently, single-phase multiferroics are far beyond any practical application, because they only demonstrate useful properties at very low temperatures. Recently, we showed that Aurivillius-type ferroelectrics doped by magnetic atoms can exhibit multiferroic behavior at room temperature. The origin of magnetism and magnetoelectric coupling in these materials, however, still needs a proper interpretation and confirmation from detailed experimental and theoretical studies. Our aim is to combine research on multiferroic materials in Slovakia with activities in China on theoretical modelling of multiferroics to design and prepare single-phase materials with the improved magnetoelectric property at room temperature.

The wear resistance improvement of tool steels surface via the laser hardening in combination with deep cryogenic treatment.
Zlepšenie oteruvzdornosti povrchu nástrojových ocelí pomocou laserového kalenia v kombinácii s hlbokým kryogénnym spracovaním.
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.
