Definition Of

A new heat-treatment system has been developed using an arc driven by an alternating magnetic field. The arc motion was theoretically investigated by the method of non-dimensional<br />analysis. After the definition of the pertinent characteristic length and time, the momentum equation was converted into the dimensionless form. This approach gave us not only a short cut to simulate the arc motion but also clear understanding on the nature of the magnetically driven arc.

In order to create a sufficiently strong material with thermo- and magneto-thermoelectric figure of merit close to single-crystal samples of material based on Bi-Sb systems, extruded samples of Bi0.85Sb0.15 solid solution were obtained and the effect of composition, heat treatment mode, grain size and tellurium impurities was investigated on their thermoelectric properties in the temperature range ~ 77-300 K and magnetic field strength H up to ~ 74∙104A/m. We managed to obtain extruded material with thermo- and magneto-thermoelectric figure of merit ~6.2∙10-3 K-1 and ~7.2∙10-3K-1 at ~ 77 K, respectively, with strengths ~ 3 times higher than the strength of single-crystal samples of this composition, which are suitable for use in low-temperature thermoelectric converters.
