The Thermal Conductivity of Metals at High Temperature

Abstract

The Forbes bar method has been modified and adapted to the problem of measuring the thermal conductivity of metals and alloys in the temperature range from 25°C to 1000°C. A mathematical analysis is presented which indicates the error involved by assuming plane isothermals in the sample. The electrical and thermal conductivities of commercial ``A'' nickel, inconel, several stainless steel alloys, and 1010 steel are reported, and the results are compared, qualitatively at least, with the theory presented by Wilson1 and Makinson.2
