Cast Microwire with High Value of Thermoelectromotive Force

摘要

The paper considers specific features of the process of casting of microwires by high-speed melt quenching. The conditions for selecting a metal–glass pair are determined to achieve the required technological and mechanical properties of microwires. The alloy of the Cu–Zr–Si–B system is investigated and its optimal composition is determined, which seems promising for casting of microwires with high thermoelectromotive force (thermo-emf) using standard technology. The thermoelectric power of the obtained microwires is more than 40 μV K_(–1), showing great promise for manufacturing of microthermocouples.
