| Development of advanced lightweight nanostructured steel and its manufacturing-easy heat processing for ultrahigh-strength applications | |
| Program: | SRDA |
| Project leader: | Prof. Ing. Iefremenko Vasyl, DrSc. |
| Annotation: | The project is aimed at the development of novel cost-saving steel for ultrahigh-strength applications (ultimatetensile stress not less than 2000 MPa under acceptable ductility/impact toughness) and the technology of its hotdeformation and heat treatment which can be easily integrated into the production lines present at the metallurgicalplants. The steel will not comprise the expensive alloying elements (Ni, Cr, Co, Mo, V), in contrast, due to using thecheaper elements (such as Mn, Si, and Al which are lighter than Fe) it will acquire the lightweight feature. The mainobjective will be reached through the formation of a multi-phase "smart" structure that can respond to the externalload by TRIP/TWIP effects leading to self-strengthening and stress relaxation. This structure will be developed bymeans of appropriate chemical composition selection and the novel processing route design based on newtechnological approaches and solutions allowing for a reduction of the processing duration, energy consumptionand using conventional "easy-in-operation" equipment. The results of the project will have a direct positive impacton the metallurgical sector as well as on the users of ultrahigh-strength steels (machine-building, constructionsector) which will benefit from the reduction of steel cost and use the production-easy (time-saving) processingtechnology. |

| INNOVATTOOLS – Inovatívne prístupy k zvyšovaniu životnosti a znižovaniu energetickej náročnosti rezných nástrojov pri spracovaní dreva v lesníctve | |
| Innovative approaches to increase the lifetime and reduce the energy consumption of cutting tools in wood processing in forestry | |
| Program: | SRDA |
| Project leader: | RNDr. Džupon Miroslav, PhD. |
| Annotation: | The project will address the issue of the use of methods and procedures for the modification of cutting tools for wood processing in forestry. The result will be an increase in their lifetime and a reduction in emissions and energy consumption of forestry machinery and equipment. The main objects of research will be tools for primary wood processing, modification and processing of forestry biomass for energy purposes, such as splitting and chipping tools, tools for cross-cutting wood, etc. The main task of the project will be the design of procedures and methods for the modification of exposed functional surfaces of the tools. Ensuring a higher quality of functional tool surfaces in the context of reducing friction and eliminating adhesion, provides a prerequisite for reducing the load on machinery equipment and thus reducing emissions and energy consumption in a given production. Analyses will be carried out on the tools – FEM analysis in order to determine the stress-strain state, on the samples analysis of the state of the material in terms of physical properties, microstructure, mechanical properties and resistance to adhesive wear in wood-metal interaction and also abrasive wear. Based on the results of the analyses carried out, innovative surface treatment procedures will be proposed for the exposed functional surfaces to guarantee an increase in their functional lifetime. These will be applied to samples and laboratory tested by relevant test procedures. From the results of the laboratory tests, a selection will be made of the most appropriate non-conventional innovative procedures, which will be applied to the tools and tested on the equipment under forestry operating conditions. In doing so, it will be observed how the modifications in question affect the energy consumption of forestry machinery and equipment. Part of the project solution will be to ensure industrial-legal protection of the original solutions. |

| Výskum odolnosti a prevencie moderných konštrukčných materiálov voči vodíkovému krehnutiu | |
| Research of the resistance and prevention of modern structural materials against hydrogen embrittlement | |
| Program: | VEGA |
| Project leader: | Ing. Falat Ladislav, PhD. |
| Annotation: | The aim of the project is to investigate the susceptibility to hydrogen embrittlement (HE) of structural metallicmaterials based on Fe (i.e. modern grades of carbon and alloy steels) as well as selected alloys or compositesbased on non-ferrous metals (e.g. Al, Cu, Mg, etc.) by the method of electrochemical hydrogen charging andmechanical testing in laboratory conditions. The microstructural conditionality of hydrogen embrittlement will be investigated on defined material states with characteristic microstructural parameters (grain size, phase composition, etc.). The possibilities of HE prevention will be investigated using available methods of surface modification (layers and coatings, surface alloying, formation of gradient structures, etc.) of basic materials inorder to apply a barrier effect against hydrogen permeability. |
