THERMODYNAMICS OF FORMATION OF COPPER-MAGNESIUM AND NICKEL-MAGNESIUM COMPOUNDS FROM VAPOR PRESSURE MEASUREMENTS
The magnesinm vapor pressures over copper- magnesium and nickel - magnesium alloys were measured by the Knudsen effusion method in the temperature range, 400 to 1100 deg K. The free energies, enthalpies and entropies of formation of Mg/sub 2/Cu, MgCu/sub 2/, Mg/sub 2/Ni/sub 2/ and MgNi/sub 2/ were c omputed from the vapor pressure data. The results indicate that the bond strengths in the nickel - magnesium compounds are appreciably greater than in the corresponding copper-magnesium compounds. (auth)
