Thermodynamic assessment of the Nd-Zn system

The Nd-Zn binary system has been optimized by CALPHAD method, using the available experimental thermodynamic and phase diagram information. The system contains eight intermetallic compounds: NdZn, NdZn2, NdZn3, Nd3Zn11, Nd13Zn58, Nd3Zn22, Nd2Zn17 and NdZn11. They were treated as stoichiometric compounds. The standard enthalpies of formation of these compounds were calculated in this work. Good agreement was obtained between the calculation and experimental results. A set of self-consistent thermodynamic model parameters was derived.
