Abstract—Strength properties of hot-pressed materials based on Bi_0.5Sb_1.5Te₃ solid solution nanostructured with graphene nanoplastics (0.15, 0.20 wt %), nanoparticles of Al₂O₃ (0.07, 0.1 wt %, SiO₂ (0.05, 0.10 wt %), and SiC (0.05, 0.1 wt %) are studied during compressive deformation. It is found that, for all materials under study, the ultimate compression strength is \(\sigma _{{\text{u}}}^{{\text{c}}}\) = 110 ± 20 MPa, the modulus of elasticity dσ/dε = 11 ± 2 GPa, ultimate strain \(\varepsilon _{{\text{u}}}^{{\text{c}}}\) = 0.8–1.6%.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
