The order-disorder transitions of stoichiometrical AB and A3B alloys werestudied by using effective-atom model based on EAM (embedded atom method) potential.
利用EAM（EmbeddedAtomMethod）势基础上的等效原子模型分析了结构稳定性与长程有序度的关系，给出了二元体系结合能与长程有序度解析关系的一般表达式，说明当量成分下AB和A3B型合金有序无序转变行为的不同，并以NiAl和Ni3Al为研究对象具体研究了其有序无序转变，从理论上解释了这两种有序金属间化合物在实验中所表现出的不同有序无序转变行为特征。
The order-disorder transitions of the dominating phase in Ti_2AlNb-based alloy,denoted as O phase,were investigated by combining sublattice model with first-principle total-energy calculations.
运用相图计算技术,预测了名义成分为Ti-22Al-27Nb的Ti2AlNb基合金在热处理过程中的相结构与相转变,得到了该合金的相转变温度、相比例和各相的成分等重要信息,将材料热力学中的亚晶格模型和第一性原理总能计算相结合,对Ti2AlNb基合金中的主要组成相—O相(有序正交相)中的合金元素在各个亚晶格上的占位分数和有序化行为进行了深入研究,表明O相的有序-无序转变属于具有连续变化特征的二级相变,预测结果与现有实验结果相当吻合。
