Specific Heat of Chromium-Iron Alloys at Room Temperature

Abstract

The specific heat of bcc iron-chromium solid solution alloys was measured at room temperature and then calculated under simplified assumptions from lattice, magnetic, and electronic terms. The magnetic atomic heat was evaluated using the simple Weiss theory. The electronic term was assumed to be equal to $\gamma T$, where the value of $\gamma$ used was that obtained earlier from low-temperature specific heat measurements. The lattice term was taken to be the same for all alloys. Reasonable quantitative agreement between the calculated and the measured values was achieved.
