Determination of Thermophysical Properties at High Temperatures by Direct Heating Methods

摘要

Thermophysical property data for arc cast tungsten and for MOD-3 carbon to about 2600 K are given. These properties include the electrical resistivity, hemispherical total emittance, normal spectral emmitance, and thermal conductivity for both materials, Lorenz function for tungsten and thermal linear expansion for MOD-3 carbon. Some data on Thornel 50 and Morganite II fiber are also presented. A brief analysis of digital data acquisition systems for the laboratory and a description of the system purchased by TPRC are included. (Author)
