Based on the general expression of the Helmholtz free energy of alloys with L12 structure obtained in previous works, we calculate the equations of the long-range order (LRO) parameter, and order-disorder transition(ODT) temperature in the Cu3Au alloy, and obtained thermodynamic quantities of Cu3Au alloy as simple functions of temperature and LRO-parameter, at pressures P = 0. Numerical results of the linear thermal expansion coefficient, isochoric and isobaric heat capacities, isothermal and adiabatic bulk modulus are in good agreement with experiments.
