The partial molar free energy of aluminum in β‐NiAl intermetallic compounds was determined from 41.3 to 67.8 at.% nickel in the temperature range from 788 to 1005°C by an EMF method. The partial molar free energy and enthalpy of nickel, the mixing free energy and enthalpy and the free energy of formation of the different compounds in the Ni‐Al‐system were calculated.
