Enthalpies of formation of the Al–Ni intermetallic compounds

The Al–Ni system has been investigated by direct reaction calorimetry at high temperatures. Enthalpies of formation of the intermetallic compounds AlNi 3, AlNi, Al 3Ni 2, and Al 3Ni were determined and compared with the available experimental values based on calorimetric and emf measurements and wit...

Zusammenfassung:The Al–Ni system has been investigated by direct reaction calorimetry at high temperatures. Enthalpies of formation of the intermetallic compounds AlNi 3, AlNi, Al 3Ni 2, and Al 3Ni were determined and compared with the available experimental values based on calorimetric and emf measurements and with the calculated values from theoretical models. X-ray powder diffraction (XRD) and electron probe microanalysis (EPMA) were used to check structural state and stoichiometry of each phase.
