Heat Capacity and Thermodynamic Functions of Ni<SUB>36</SUB>Nb<SUB>24</SUB>Zr<SUB>40</SUB> Glassy Alloy

Abstract

The heat capacity of a Ni 36 Nb 24 Zr 40 glassy alloy was measured by adiabatic calorimetry from 13 to 300 K. The smoothed values of molar heat capacity were calculated from the data using a least-squares method. The standard enthalpy, entropy, and Gibbs energy were calculated from the smoothed heat capacity values. Assuming H(0) = 0 and S(0) = 0 at 0 K, the heat capacity, enthalpy, entropy, and Gibbs energy at 298.15 K are 24.91 J·K ―1 ·mol ―1 , 5.252 kJ·mol ―1 , 36.45 J·K ―1 ·mol ―1 , and ―5.615 kJ·mol ―1 , respectively.
