Abstract
Electrical conductivity and thermo-electromotive force measurements were performed for a liquid binary Pb83Mg17 eutectic and Pb83Mg17–xMx alloys (x ≤ 3 at.%; M = Al, Ga, Ni, Bi, Cu) at temperatures up to 1300 K under pressures of argon gas (up to 50 MPa) using the four-probe method. It was revealed that small amounts of a third component affect significantly the electrophysical properties. The influence of these additions on the electrical conductivity and thermo-electromotive force is discussed briefly. Possible applications of such alloys have been proposed.
Abstract
Mit Hilfe einer Vier-Draht-Methode wurden die elektrische Leitfähigkeit und die Thermokraft flüssiger Mg83Pb17- und Pb83Mg17–xMx-Legierungen (x ≤ 3 at.%; M = Al, Ga, Ni, Bi, Cu) im Temperaturbereich bis 1300 K unter Ar-Drücken bis 50 MPa untersucht. Es wird diskutiert, wie der Zusatz einer dritten Komponente das Verhalten der elektrischen Leitfähigkeit und der Thermokraft beeinflußt. Mögliche Anwendungen solcher Legierungen werden vorgeschlagen.
