Abstract
The specific heat of FCC Fe-Cr-Ni alloys has been determined in an adiabatic calorimeter between 300 and 1200K. The experimental curves reveal two anomalous maxima at 500K and 800-900K with only a weak concentration dependence. The anomalies can be interpreted by thermally excited electron transitions with energy gaps corresponding to absorption bands that have been found in the infra-red absorption spectrum.Keywords
