Methods of extrusion are widely used in technology of thermoelectric (TE) materials manufacturing with high strength and good TE properties at temperatures above 200 K. The method of extrusion of Bi - Sb single crystals in the liquid environment under high hydrostatic pressure is considered. The construction of experimental equipment is presented. It was shown that presented method of extrusion allows preparing of polycrystalline material with high TE and improved strength properties at temperatures below 180 K.

Effect Of Hydrostatic Pressure

ABSTRACTThe effect of the pressure 550MPa on the choice of the acting slip plane in the single crystals of Fe−2,9%Si was studied. It was established that the presence of pressure resulted in the increase of the slip asymmetry. The effect of pressure is attributed to the action of normal stresses and to the special structure of screw dislocations.

Diffusion Coalescence

The effect of high hydrostatic pressure on the relaxation of the electrical resistivity at room temperature of oxygen-nonstoichiometric [Formula: see text] (Re = Y, Ho) single crystals is investigated. The application of hydrostatic pressure has been revealed to significantly intensify the process of diffusion coalescence in the oxygen subsystem. At the same time, the intensity of the redistribution of labile oxygen is significantly changed when yttrium is replaced by holmium.

Mn Concentration

We have studied single crystals with same La/Sr ratio but different initial Mn concentration, namely (La0.85Sr0.15)0.93MnO3and (La0.85Sr0.15)0.97MnO3. We have observed, that the temperature of insulator-metal transition TIMincreases for both samples and the temperature of charge ordering TCOincreases for (La0.85Sr0.15)0.93MnO3and decreases for (La0.85Sr0.15)0.97MnO3with the external hydrostatic pressure in the range of 0.1 MPa - 1.3 GPa. After analysis of obtained dependence, we have concluded that (La0.85Sr0.15)0.97MnO3sample has higher concentration of Mn vacancy. Thereby we suppose that growth of Mn vacancy concentration decreases transfer interaction of the conducting electrons and enhances charge ordering of Mn3+and Mn4+ions.
