Description
Summary:This paper reports an x-ray diffraction, scanning and transmission electron microscopy study of regularities in the formation of defect structures in thermoelectric materials at different stages of plastic flow during equal-channel angular pressing in a three-channel configuration. We show that this deformation setup produces a homogeneous fine-grain structure with a preferential texture in which grain cleavage planes arrange along the extrusion axis. These studies of the structure and properties of thermoelectric materials were used to choose the optimum temperature for equal-channel angular pressing corresponding to lower pre-recrystallization temperatures.
