根据已有的文献数据，包括相平衡和热力学性质，采用相图计算方法，对Ti-Ir二元体系的吉布斯自由能进行了模拟计算。采用Redlich-Kister亚规则溶液模型描述了液相、bcc、fcc和hcp相的Gibbs自由能，采用双子格模型描述了Ti-Ir二元系中金属间化合物（Ti 3 Ir、γTiIr、βTiIr和TiIr 3）的Gibbs自由能。计算结果与Ti-Ir体系的相平衡和热力学性质的文献数据吻合良好。
The thermodynamic assessment of the binary system Ti-Ir has been carried out by modeling the Gibbs energy of all individual phases using the calculation of phase diagrams approach based on the available literature data including the phase equilibria and thermodynamic properties. The Gibbs free energies of the liquid, bcc, fcc and hcp phases were described by the subregular solution model with Redlich-Kister formula, and those of the intermetallic compounds (Ti3Ir, γTiIr, βTiIr and TiIr3) in the Ti-Ir binary system were described by the two-sublattice model. The calculations are in good agreement with the literature data on both phase equilibria and thermodynamic properties in the Ti-Ir system.
