Thermoelectric Power and Resistivity of Chromium-Rich CrFe Alloys between 25° and 1000°C

A study has been made of the thermoelectric powers (S) and electrical resistivities (ρ) of CrFe alloys over the concentration range 0 to 48.2 at. % Fe and temperature (T) range from 25° to 1000°C. The plots of S vs T and ρ vs T move in an orderly progression from that of pure Cr to the curve for the Cr51.8Fe48.2 alloy with no anomalies occurring. One might think that S should change sign as the alloy concentration passed through the region where Beck et al. observed their ``spike'' in the electronic specific heat, but no such phenomenon was observed.
