Thermodynamic modeling of the Co–Sm system
Source abstract
Abstract
Abstract The phase diagram of the Co–Sm system has been assessed by applying the Calculation of Phase Diagram (CALPHAD) technique. Thermochemical and phase equilibrium information from the literature have been critically evaluated, and a series of self-consistent thermodynamic parameters capable of describing the Gibbs free energies of each phase of the system has been obtained. There are eight compounds in this system. Based on an analysis of experimental data and the crystal structures of the phases, SmCo 5 was modeled as (Co,V a) 0.833333 (Co 2 ,Sm) 0.166667 and Sm 2 Co 17 as (Co) 0.833333 (Sm) 0.111111 (Co 2 ,Sm) 0.055556 . The remaining six intermetallic phases, Sm 3 Co,Sm 9 Co 4 , SmCo 2 , SmCo 3 , Sm 2 Co 7 , and Sm 5 Co 19 , were treated as stoichiometric compounds. Calculations based on these parameters can reproduce most of the experimental data very well.
