摘 要: 采用固液反應(yīng)球磨專利技術(shù)制備Fe-Sn金屬間化合物。 所謂固液反應(yīng)球磨, 是在一定溫度區(qū)間， 球磨介質(zhì)對金屬液體進行球磨時，磨球和金屬液體反應(yīng)生成固相的金屬間化合物粉末。 為加速反應(yīng)進行， 可以在金屬液體中加入與磨球成分相同的金屬粉末。 通過固液反應(yīng)球磨制備了FeSn2， FeSn， Fe3Sn2和Fe1.3Sn 4種金屬間化合物納米粉末，并對固液反應(yīng)球磨技術(shù)制備金屬間化合物的機理和特點進行了討論。

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，F(xiàn)eSn，F(xiàn)e3Sn2 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
