In recent years, with the development of modern material preparation technology, the application prospects of Fe-Ga alloy have become increasingly broad. Among them, the influence of non-equilibrium solidification on the magnetostrictive properties of Fe-Ga alloy has become a hot research topic in the field of material science. In this paper, the influence of non-equilibrium solidification on the magnetostrictive properties of Fe-Ga alloy is studied in depth.Methods:In this study, Fe-Ga alloy samples were prepared by a rapid solidification technique, and the microstructure and phase composition of the samples were analyzed by X-ray diffraction and scanning electron microscopy. The magnetostrictive properties of the samples were measured by the magnetostrictive tester to reveal the relationship between non-equilibrium solidification and magnetostrictive properties.Results and Discussion:The results showed that non-equilibrium solidification could significantly affect the magnetostrictive properties of Fe-Ga alloy. The rapid solidification process could promote the formation of fine and uniform microstructures and reduce the number of defects in the samples, which could significantly improve the magnetostrictive properties of Fe-Ga alloy. Moreover, by adjusting the process parameters and optimizing the alloy composition, the magnetostrictive properties of Fe-Ga alloy could be further improved.Conclusion:The study revealed the significant influence of non-equilibrium solidification on the magnetostrictive properties of Fe-Ga alloy, which provided a theoretical basis for the optimization of the preparation process and the improvement of the application performance of Fe-Ga alloy. The research results have practical significance for the development and 精品文档---下载后可任意编辑application of Fe-Ga alloy in high-tech fields such as robotics and precision machining.
