Influence of Rear Earth Yb on the Specific Heat of Liquid Fe-Co-Yb Alloy

Abstract:

By Monte Carlo method with EAM potentials, the specific heat of liquid Co₅₀Fe₅₀ and Co₄₈Fe₄₈Th₄ alloys at different temperatures are obtained. The effect of Th on the thermophysical parameters is examined. Over the temperature range from 1400 to 2000 K, the specific heat decreases from to Jmol^-1K^-1 after Th was added. It is the addition of Th element which has bigger atomic radius, larger atomic mass, and complex arrangement of extranuclear electron, leads to the reduced specific heat.
