According to the VESs analysis, the intrinsic brittleness of Fe〓Al is due to less lattice electrons, bondcomplex distribution heterogeneity, hydrogen-induced embrittlement, and the difficulty in recovery of the lattice symmetry, while various alloying elements have strengthening and toughening effects through altering the VES parameters.

运用固体与分子经验电子理论建立起Fe〓Al合金各相的价电子结构，在计算中，首次尝试利用TFD模型确定Fe〓Al的原子杂阶，针对不完全有序的B2-Fe〓Al提出"局部平均原子模型"，对Fe〓Al的室温脆性从电子理论上进行了系统的阐述，认为较少的晶格电子、键络分布不均匀、氢致脆性和难以恢复晶体的对称性使Fe〓Al具有本质脆性，合金化元素可以在一定程度上改变价电子结构参数而改善强度和韧性。

In order to reach the purpose of using pre-laser cladding method preparation of Ni-based amorphous alloy coatings on 45 steel substrate surface by the method was carried out. The principles of the three clusters and the amorphous line of the law of composition rules were used. The Ni59.35Nb34.45Sn6.2 alloying powder which has a great glass-forming ability in conventional preparation methods of amorphous alloys was chosen. In the protection of atmosphere, the amorphous surface coating was prepared. The microstructure, micro-hardness and performance of the different output power of the laser cladding were analyzed.
