Abstract:A novel patent technology, defined as solid-liquid reaction milling was employed to prepare Fe-Sn intermetallic powders. The so-called solid-liquid reaction milling is a method of preparing the solid-state intermetallic compound powders by the reaction between the milling medium and the liquid-state metal at a certain temperature range. To accelerate the reaction, some element powders with the same composition as the milling medium can also be added. FeSn2，FeSn，Fe3Sn2 and Fe1.3Sn nanocrystalline powders were fabricated by the solid-liquid reaction milling. The reaction mechanisms and advantages were discussed.
Key words: solid-liquid reaction milling; intermetallic compounds; nanocrystalline
