description: The topic of the final qualifying work: "Study of the structure and physical properties of thermoelectric BiSbTe alloys". This work is devoted to the study of the structure and physical properties of thermoelectric BiSbTe alloys. During the study, the following tasks were identified: 1. Conducting phase analysis of characteristic zones, as well as shooting with discrete rotation of the sample. 2. Investigation of the relationship between metallographic analysis and the phase composition of the material. 3. Identification of zones with high and low dispersion along the section of the extruded sample. 4. Establishing the relationship between the stress-strain state of the material and the formation of various crystallographic structures using mathematical modeling. To solve the tasks set, a number of physical and mathematical studies were carried out: the phase composition of characteristic zones, shooting with discrete rotation of the sample, metallographic analysis, mathematical modeling of the extrusion process by the finite element method and investigation of the thermoelectric properties of the material by the probe method. The results obtained made it possible to form the main conclusion that the structure of the extruded rod has an inhomogeneous distribution of thermoelectric properties over the cross section, due to the heterogeneity of the stress-strain state and the disorientation of the crystallites.
