By means of CALPHAD technique, the Co-Pr, Er-Ni and Ni-Pr systems were crit
ically assessed. The solution phases (liquid, bcc, fcc, hcp and dhcp) are m
odeled with the Redlich-Kister equation, and the intermetallic compounds tr
eated as stoichiometric compounds. Self-consistent thermodynamic parameters
of the Co-Pr, Er-Ni and Ni-Pr systems were obtained. The calculations agre
e well with experiments. (C) 1999 Elsevier Science S.A. All rights reserved
