中文摘要：

以便获得对 Mg-Ga 二进制系统的热力学的描述，对系统的热力学的评价通过 Thermo 计算用 CALPHAD 方法被执行？软件包裹基于从出版文学的所有可得到的试验性的数据的评估。答案阶段包括液体， hcp (Mg ) 并且斜方晶(Ga ) ，被代理答案模型，过量吉布斯精力与 Redlich-Kister 多项式被表示描述。同时，所有金属间化合的混合物， Mg5Ga2， Mg2Ga， MgGa， MgGa2 和 Mg2Ga5，作为 stoichiometric 混合物被建模。在 Mg-Ga 二进制系统提出各种各样的阶段的吉布斯精力的一套前後一致的热力学的参数最后被获得。好一些的协议在计算结果和报导试验性的数据之间被完成。

英文摘要：

In order to obtain the thermodynamic description of the Mg-Ga binary system,the thermodynamic assessment of the system was carried out using the CALPHAD method through Thermo-calc software package based on the evaluation of all available experimental data from the published literature.The solution phases,including liquid,hcp（Mg） and orthorhombic（Ga）,were described by the substitutional solution model,of which the excess Gibbs energies were expressed with the Redlich-Kister polynomial.Meanwhile,all intermetallic compounds,Mg5Ga2,Mg2Ga,MgGa,MgGa2 and Mg2Ga5,were modeled as stoichiometric compounds.A set of self-consistent thermodynamic parameters formulating the Gibbs energies of various phases in the Mg-Ga binary system were obtained finally.The much better agreement is achieved between the calculated results and the reported experimental data.
