本文对用电流体动力学法制取的Ｓｎ－Ｂｉ纳米晶粉进行微区原位电子显微综合实验，发现获得的Ｓｎ－Ｂｉ纳米晶粉是具有单晶结构的β－Ｓｎ式Ｂｉ的单相过饱和固溶体（或单相固溶体），对其形成机制进行了分析

The microstructure of Sn-Bi nanometer powder prepared by the electrohydrodynamic technique has been examined in site on the analytical transmission electron microscope. It was found that each Sn-Bi nanometer powder particle is either β-Sn or supersaturated Bi with the structure of single crystal. The formation mechanism of Sn-Bi nanometer powder has been analysed.(Correspondent: LIU Xiang, professor, Departments of Materials Science, Northeastern University, Shenyang 110006 )
