应用修正嵌入原子法（ＭＥＡＭ）研究了Ｆｅ－Ｍｎ二元合金中γ相（ｆｃｃ）和α（ｂｃｃ）随Ｍｎ含量变化的不同能量，它们的能量变化趋势与Ｆｅ－Ｍｎ二元相图的推测结果一致．由此表明，用ＭＥＡＭ法研究Ｆｅ－Ｍｎ二元系中两种立方相的能量是有效的．
The different energies of γ phase (fcc) and α (bcc) with the change of Mn content in Fe-Mn binary alloys were studied by using Modified Inlaying Atom Atom (MEAM). The trend of their energies and the prediction of Fe-Mn binary phase diagram The result is the same. This shows that it is effective to study the energy of two cubic phases in the Fe-Mn binary system by the MEAM method.
