The anisotropic elastic properties, topology structure of brittleness and the transformation of edge dislocations in Ti₃Al are studied in detail based on Bond matrix model and the tensor theory of elastic media. The results contain remarkably complex three-dimensional variations in the anisotropy and brittleness with angular distribution. The feature of elastic properties and brittleness in Ti₃Al is affected by the elastic anisotropy of the lattice. Their topology surfaces give insights into the relationship between elastic anisotropy and brittleness. It is helpful to understand the dislocation field through comparative study of the edge dislocation in the dislocation coordinate system and crystal coordinate system with tensor theory as well as the Bond matrix model.

基于Bond矩阵模型和弹性介质张量理论，对Ti ₃ Al的各向异性弹性特性、脆性拓扑结构和边缘位错的转变进行了详细研究。结果包含各向异性和脆性随角度分布的非常复杂的三维变化。_{Ti 3} Al的弹性特性和脆性特性受晶格弹性各向异性的影响。它们的拓扑表面可以深入了解弹性各向异性和脆性之间的关系。通过张量理论和邦德矩阵模型对位错坐标系和晶体坐标系中的边缘位错进行对比研究，有助于理解位错场。
