Influence of phase transitions in AuCu on thermal diffusivity and thermal conductivity
RUDAJEVOVA, A.
vol. 40 (2002), no. 6, pp. 365 - 370

Abstract
Measured thermal diffusivity of AuCu alloy at temperatures 20-550 °C is presented and analysed. Thermal conductivity of ordered and disordered AuCu alloy was calculated as a product of the thermal diffusivity, specific heat and density. By using Wiedemann-Franz law and literature data for electrical resistivity, electronic and phonon thermal conductivities were calculated for ordered and disordered phases. While the phonon thermal conductivity is nearly the same for the ordered and disordered AuCu alloy, the electronic thermal conductivity of the ordered alloy is almost three times larger than that of the disordered one.

Key words
intermetallic alloys, phase transitions, thermal diffusivity, thermal conductivity
