采用电磁悬浮熔炼结合助熔剂法，通过过热-冷却循环，将Fe_（83）Ga_（17）合金过冷至173 K。结果表明，显微组织与过冷度密切相关。当过冷度低于53 K时，组织由粗大的枝晶和枝晶间的暗色颗粒组成。随着过冷度的增加，凝固组织趋于完整，晶粒具有择优取向。[100]取向的织构在过冷过程中形成。热处理冷却速度对Fe_（83）Ga_（17）合金的显微组织有显著影响。水淬工艺抑制了DO 3相的析出，炉冷过程中冷却速度过慢会导致亚稳相DO 3的形成。
Using electromagnetic levitation melting combining with fluxing method, the Fe83Ga17alloys were undercooled up to 173K through superheating–cooling cycles. The results showed that the microstructure was closely related to the undercooling. When the undercooling was lower than 53K, the structures consisted of coarse dendrites and some dark particles in interdendrite. With the increase of undercooling, the solidified microstructures tended to be integrated, and the grain had preferred orientation. The texture of [100] orientation were developed by the undercooling process. The cooling rate of heat treatment significantly affects the microstructure of Fe83Ga17alloys. The water-quenched process could restrain the precipitation of DO3phase, and the low cooling rate in the process of furnace cooling could lead to form the metastable DO3phase.
