Polycrystalline Fe <sub>81</sub> Ga <sub>19</sub> alloy with magnetostriction comparable single-crystals prepared via laser powder bed fusion in-situ remelting
This study introduced the laser additive manufacturing strategy of an Fe-Ga alloy with magnetostriction of comparable to single crystal. The Fe81Ga19 alloy is fabricated by in-situ laser remelting in the laser powder bed fusion. It is found that not only the direct precipitation of L60 nanoprecipitates is achieved by the laser remelting strategy, but also its distribution, density, and size are controlled by the optimized process. At the same time, remelting enhances the easy magnetization direction [Formula: see text] orientation of the Fe81Ga19 alloy. With this synergistic effect, the magnetostriction of the oriented polycrystalline Fe81Ga19 alloy reaches 208 ppm.
