RESEARCH ON ELECTRICAL CONDUCTORS FOR HIGH TEMPERATURE APPLICATIONS.
Abstract
Dispersion-hardened alloys of Pt, Au, and Cu containing ThO2 and Al2O3 were made and tested. The allows were developed and fabricated in wire form in order to provide high temperature electrical conductor materials providing improved mechanical properties with a minimal loss in electrical conductivity. The alloys were made by precipitating the elements from solution containing a suspension of the oxide phase. The precipitate deposited on the oxide particle and produced a dispersion of good homogeneity. Mechanical properties and electrical resistivities were measured as a function of temperature to 1000 C. The dispersion hardening caused only negligible (<5%) rises in the resistivity of the alloy compared to the resistivity of the pure metal. Alloys containing less than 2V% oxide phase had sufficient ductility to permit fabrication into wire. (Author)
