abstract = {The vaporisation of Fe-Al and Ni-Al alloys has been
investigated in the temperature range 1140-1600 K and 1178
to 1574 K, respectively, by Knudsen effusion mass
spectrometry (KEMS). Eleven different Fe-Al and also eleven
Ni-Al compositions have been investigated in the composition
ranges 30-51 $at.\%$ Al and 38-53 $at.\%$ Al, respectively.
The Fe Al samples have been investigated mostly in the B2
region of the phase diagram. The partial pressures and
thermodynamic activities were evaluated directly from the
measured ion intensities formed from the equilibrium vapour
over the alloy and the pure element. From the temperature
dependence of the activities the partial and integral molar
enthalpies and entropies of mixing have been obtained. These
are the most accurate data obtained by mass spectrometry on
Fe-Al and Ni-Al systems so far. Nearly temperature
independent integral enthalpies and entropies of mixing over
the wide temperature range investigated were found, with the
mixing entropies being large and negative. (C) 2003 Elsevier
