The work will be focused on the study of phases, phase equilibria and phase diagrams in the systems for high-temperature applications. The aim is to refine the uncertainty of phase diagrams and investigate unknown parts of selected binary systems by experimental methods of differential thermal analysis, X-ray diffraction and electron microscopy and then to model their phase diagrams and thermodynamic properties using the semi-empirical Calphad-method. The subjects of the study are binary systems with iridium. Iridium is an element which, due to its thermodynamic properties, is very interesting for use in the aerospace industry and due to its high corrosion resistance even at very high temperatures, it may potentially be suitable for use as part of gas turbine materials. The results of the thesis will allow extending the possibility of designing new materials for high-temperature use by computational methods without the need for time-consuming experimental testing.
