Paper Abstract

In present work study of dependencies of transional contacts rk of extruded samples Bi85Sb15 solid solution with the alloy mass.%: 57Bi + 43Sn with melting temperature Tm approximately equals 412 K on the intensity of magnetic field and temperature. This contact alloy is broadly use at commutation of thermoelements on the base Bi-Sb system solid solution. At the fixing of contact on torahs of extruded samples Bi85Sb15 occurs a mutual diffusion of components of solid solution and contact alloy each to other. So as a result of diffusions of atoms Sn from the contact alloy in Bi85Sb15 solid solution near the contact appears near-contact layer of given solid solution, doped by atoms of tin. By doping near contact layer of branches of thermoelements on the base of Bi85Sb15 solid solution with donor impurities, compensating action of acceptor atoms, diffusing from the contact alloy in this layer, possible vastly lower rk and raise efficiency of thermoelements.
