The structural features of massive castings (up to 20 tons) are revealed in the process of crystallization and operation under the temperatures of magnetic transformation of the carbide phases (magnetostriction phenomenon). A new approach to characterization of structure formation in a multiphase alloy with the optical-mathematical method for the description of metallographic images is proposed.

In the present work, the efficiency of pulsed photon processing in increasing the hardness and adhesive strength of the surface of hot-pressed semiconductor thermoelectric branches based on the Bi2Te3-Bi2Se3 (n-type) and Bi2Te3-Sb2Te3 (p-type) solid solutions. This is achieved by stimulating local recrystallization of the defective layer near the surface of semiconductor branches at a depth of 100-200 nm.
