本文对Al-Mn二元系进行了热力学计算，计算中考虑了五种金属间化合物和所有的固溶体相，体心立方（bcc）相的吉布斯自由能也采用了考虑二级A_2/B_2有序化反应的双子格模型，一组一致的优化的热力学参数已经到达描述在该系统中的每个相的吉布斯自由能，导致计算和实验之间的更好的拟合。
A thermodynamic calculation of the Al-Mn binary system that takes into account recent experimental results and includes five intermetallic compounds and all the solid-solution phases is presented, The Gibbs energy of the body-centered cubic (bcc) phase has been described on the basis of the two-sublattice model that includes the second-order A2/B2 ordering reaction as well, A consistent set of optimized thermodynamic parameters has been arrived at for describing the Gibbs energy of each phase in this system leading to a better fit between calculation and experiments.
