The main idea of this work is to design the microstructure of nanostructured austenitic steel to improve its antibacterial and mechanical properties. In the literature, antibacterial properties are primarily attributed to the chemical composition of metals and their alloys, rather than their microstructural features. Therefore, the planned research is highly innovative. The severe plastic deformation (SPD) will be applied to produce the nanostructured material. The microstructure will be further optimized through annealing. The use of advanced electron microscopy methods will allow for a precise characterization of the resulting microstructures. The doctoral thesis will be carried out as part of a National Science Centre (NCN) project.

High entropy alloys are interesting group of materials which feature unexpected properties as a result of specific atomic arrangements. Recent studies have shown that chemical short range ordering, as well as interstitial atoms could significantly improve mechanical performance of such materials. Proposed project will focus on the designing (with use of computer simulations), manufacturing and characterization of CrFeMnNi alloys with oxygen or nitrogen additions. Additionally, heat treatment which induce short range ordering is planned to be designed. Mechanical properties studies will be complemented with detailed analysis using electron microscopy techniques.

The proposed doctoral thesis topic concerns the influence of LPBF printing strategies on the microstructure and resistance to hydrogen interaction of a multi-phase cermet produced by additive manufacturing. The research subject arises from the growing interest in materials that combine the high mechanical strength of ceramic phases with the functional properties of metallic phases, as well as the dynamic development of additive manufacturing technologies that enable the production of such materials.
