Thermal conductivity, electrical resistivity and Seebeck coefficient of high purity iron and selected iron alloys from 90 K to 400 K. [Fe--1. 14 Cr, Fe--2. 96 Cr, Fe--1. 15 Cr--1. 30 Ni, and Fe--3. 15 Ni]
The thermal conductivity, electrical resistivity, and Seebeck coefficient of high-purity iron, two iron--chromium alloys, one iron--nickel alloy, and one iron--chromium--nickel alloy were measured over the temperature range from 90 K to 400 K. Smoothed values for the thermal conductivity and electrical resistivity were used to calculate the electronic thermal conductivity, the lattice conductivity, and the Lorenz function by means of a binary alloy separation technique. The lattice conductivity and Lorenz function exhibited little change due to the addition of chromium; however, the addition of small amounts of nickel resulted in significant property changes. The lattice conductivity at high temperatures wasmore »
