Abstract
Vaporisation studies on Al–Ni alloys with x(Ni) = 0.43, 0.42, 0.35, and 0.32 were carried out by Knudsen effusion mass spectrometry. Partial pressure-temperature relations of Al(g) over the two phase regions {AlNi + Al3Ni2} and {Al3Ni2 + Al3Ni} were determined in the temperature ranges 1104 – 1278 K and 1021 –1122 K, respectively. The corresponding equations are log(p(Al)/Pa) = –(20 039 ± 84)/T(K) + (13.464 ± 0.070) for {AlNi + Al3Ni2} and log(p(Al)/Pa) = – (16 836 ± 235)/T(K) + (11.345 ± 0.219) for {Al3Ni2 + Al3Ni}. The vaporisation reactions, Al3Ni2.025(s) = 2.6436AlNi0.766(s) + 0.3564Al(g) and Al3Ni(s) = 0.572Al3Ni1.747(s) + 1.284Al(g) were evaluated and subsequently the enthalpy and Gibbs energy of formation of Al3Ni1.747(s) were derived.
