摘要
研究通过Cu球对液态金属Sn在不同温度及时间内球磨制备Cu-Sn金属间化合物的过程,采用X射线和扫描电镜及透射电镜等分析手段分析产物特征。结果表明,在球料比为10∶1,转速为80r/min的条件下,用Cu球对液态Sn进行不同时间及温度的液态球磨后,得到了不同的金属间化合物。在400℃时金属间化合物为Cu6Sn5,500℃及600℃时产物为Cu3Sn。加铜粉可以加快反应速度。采用固液反应球磨技术在高温下可以形成粒度很小,甚至达到纳米级的金属间化合物粉末。与机械合金化相比,固液反应球磨技术生成金属间化合物的速度较快,且成分单一。
The solid-liquid reaction milling technology for Cu-Sn intermetallic powder preparation at different temperature ＆ retention time is investigated, and the microstructure is analyzed by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The results indicate that the different intermetaUics are formed by the reaction milling of Cu ball and molten Sn at different temperature with 10 ： 1 ratio of ball to molten Sn and 80r/rain rounding speed. The Cu6Sn5 is formed at 400℃ and Cu3Sn is formed at 500℃ and 600℃, and the reaction rate is accelerated by the addition of the copper powder. The particle size of the powder from solidliquid reaction milling is fine, even though reaches to nanoscale. The reaction rate is fast and the composition of the intermetallics is unitary comparing to the mechanical alloying process.
