Anotace
The purpose of theoretical (Czech) part of the project is to perform ab initio electronic structure calculations for MoSi2, WSi2/ a TiSi2, to determine their theoretical strength as well as to analyze their stability and phase transformations and to apply the calculated results to a more detailed interpretation of experimental results obtained in the group of the Japanese partner, prof. Inui from the Kyoto University. The main goal of the project is to find optimum orientations of single crystals of transition-metal disilicides for loading in uniaxial tension and pressure (i.e., those orientations for which the strength of the single crystals attains the maximum value) and to gain a deeper insight into mechanical properties of these materials.
