Rogacheva [et al.] // Journal of Physics and Chemistry of Solids. – Electronic text data. – 2020. – Vol. 143 – P. 109431. – URL: https://www.sciencedirect.com/science/article/abs/pii/S0022369719311163?via%3Dihub#abs0010, (date of application 31.01.2023).https://repository.kpi.kharkov.ua/handle/KhPI-Press/61903The dependences of microhardness H, electrical conductivity σ, charge carrier mobility μH, the Seebeck coefficient S, and thermoelectric power factor P = S2σ on the composition of Bi1-xSbx solid solutions in the vicinity of pure Sb (x = 1.0–0.975) were obtained. In the range of x = 0.9925–0.9875, an anomalous decrease in H and S and increase in σ and μH with increasing Bi concentration were observed. For all the alloys, the dependences of H on the load on an indenter G were plotted. It was found that the H(G) dependences for samples with x smaller than ~ 0.99 and for samples with x exceeding 0.99, exhibit different behavior. The results obtained are interpreted on the basis of our assumption about the existence of a percolation-type phase transition from impurity discontinuum to impurity continuum that occurs in any solid solution.enalloysmechanical propertiestransport propertiesphase transitioncritical phenomenaArticledoi.org/10.1016/j.jpcs.2020.109431https://orcid.org/0000-0001-7584-656Xhttps://orcid.org/0000-0002-9638-7080https://orcid.org/0000-0003-2578-1109
