Knudsen Effusion Mass Spectrometric studies on Ni-Al System: Vaporisation Studies over {AlNi+Al3Ni2 and {Al3Ni2+Al3Ni} - Dedicated to Professor Dr. Fritz Aldinger on the occasion of his 65th birthday
Knudsen Effusion Mass Spectrometric studies on Ni-Al System: Vaporisation Studies over {AlNi+Al3Ni2 and {Al3Ni2+Al3Ni} - Dedicated to Professor Dr. Fritz Aldinger on the occasion of his 65th birthday
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 AI(g) over the two phase regions {AlNi + Al3Ni2} and {Al3Ni2+Al3Ni} were determined in the temperature ranges 1104-1278 K and...

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 AI(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) = -(16836 +/- 235)/T(K) + (11.345 +/- 0.219) for {Al3Ni2 + Al3Ni}. The vaporisation reactions, Al3Ni2.025(s) = 2.6436AINi(0.766)(S) + 0.3564Al(g) and Al3Ni(s) = 0.572Al(3)Ni(1.747)(S) + 1.284Al(g) were evaluated and subsequently the enthalpy and Gibbs energy of formation of Al3Ni(1.747)(s) were derived. |
