The transmission of ultrasound vibrations during welding leads to changes in the welding zone. The microstructure has a significantly reduced width of the dendritic zone than in the reference specimen.

the studies carried out show that by varying the nature of the solvent, the concentration and nature of the polymers in the initial solutions, it is possible to control the structure formation in mixed polymer solutions, and, therefore, the properties of the resulting composites.

Thermoelectric materials are designed according to thermoelectric characteristics, which require good agreement with the Zeebeck coefficient, electronic conductivity, and thermal conductivity. This paper is presented the comparative data of thermal properties in five compounds of nanocrystalline copper sulfides KxCu1.85S (0<x <0.05) at the temperature zone from 300 K to 700 K. X-ray phase analysis shows a mixture different phases of copper sulfides such as Сu1.85S cubic phase, Cu2S cubic phase, Cu17S9 (Cu1.89S) rhombohedral phase, Cu2S tetragonal phase in all investigated compounds at room temperature. The sizes of crystallites in the alloys estimated from half-width of X-ray lines are in range from 24 to 90 nm. The thermal conductivity of alloys decreases to 0.2 ÷ 0.6 W K-1m-1 in temperature range of 350 – 700 K due to increasing of the amount of potassium (for x = 0.04, 0.05). This guides the maximum thermoelectric characteristics of the material. The obtained results are important for semiconductor materials used in the field of thermoelectric devices.
