摘要：
On the basis of available experimental information, the Nd-Zn binary system has been thermodynamically optimized using the CALPHAD method. The solution phases, liquid, bcc and dhcp, were treated as substitutional solutions, while the intermediate compounds, NdZn, NdZn(2), NdZn(3), Nd(3)Zn(11), Nd(13)Zn(58),Nd(3)Zn(22), Nd(2)Zn(17) and NdZn(11), were described as stoichiometric phases. A set of self-consistent parameters formulating the Gibbs energies of various phases in this binary system was obtained. Most of experimental data on thermochernistry and phase diagram reported in the literatures were satisfactorily reproduced. (c) 2007 Elsevier B.V. All rights reserved.
