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 to investigate unknown parts of selected systems by experimental methods of differential thermal analysis, X-ray diffraction and electron microscopy and subsequently to model their phase diagrams and thermodynamic properties using the semi-empirical Calphad-method. The subjects of the study are ternary systems containing mainly refractory metals and boron as the basis of materials potentially suitable for high-temperature use. 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.
