Intermetallics and Advanced Alloy Properties

Using different calorimeters, the following measurements have been carried out: (i) the determination of the integral enthalpy of mixing of binary liquid MgNi and ternary liquid CuMgNi alloys; (ii) the determination of the heat capacity of the intermetallic compounds CuMg2, Cu2Mg, Mg2Ni and MgNi2; (iii) the determination of the enthalpy of fusion of the intermetallic compounds CuMg2 and Cu2Mg. An association model is used to calculate the thermodynamic functions of mixing of liquid CuMg and MgNi alloys and the phase equilibria of the MgNi system. The thermodynamic functions of the liquid CuMgNi alloys are calculated using the model parameters of the base binary systems.
