Thermodynamic assessment of the dysprosium-gold binary system

Phase relationships in Dy-Au binary system has been thermodynamically assessed by using the CALPHAD technique. Liquid and the solution phases, fcc_A1, bcc_A2 and hcp_A3, were treated as a substitutional solution model. The binary intermetallic compounds are treated as stoichiometric phases. All the thermodynamic parameters of various phases have been optimized and the calculated results are confronted with experimental data.
