| Abstract Scope |
A novel phenomenological framework for an efficient estimation of the thermo-
electric properties at room temperature and elevated temperatures of body-
centered cubic (BCC) transition element concentrated alloys is proposed in this
work. The methodology is used to predict the electrical resistivity of BCC high
entropy alloys and our predictions show excellent correlation with experimental
data. This framework is further extended to predict the electrical resistivity ρ,
thermal conductivity κ and the specific heat capacity Cp of BCC transition alloys
in the temperature range of 300 K - 1300 K and the results are validated against
experimental data. Finally, we use this model to design two ternary concentrated
transition-metal alloys (W53Ta42V5 and Nb40Mo40Ta20) and predict their
thermo-electric properties in the same temperature regime, with W53Ta42V5
designed to exhibit a zero temperature coefficient for ρ and the Nb40Mo40Ta20
alloy is expected to retain a near constant value of κ. |
