本工作描述了在超声作用下熔融铋与其它低熔点金属（Sn，In，Ga和Zn）的相互作用。将铋和这些金属中的一种的二元组合在热硅油中熔融在一起，并用超声能量照射以形成微米/纳米合金颗粒。分析了这些颗粒的形貌、组成和晶体结构。发现铋与锡和锌形成金属基质复合物，与铟形成金属间化合物，与镓形成合金。我们还通过X射线衍射（XRD）、差示扫描量热法（DSC）和电子显微镜观察了体系的结构变化。
This work describes the interactions of molten bismuth with other low-melting point metals (Sn, In, Ga and Zn) under sonication. Binary combinations of bismuth and one of these metals were melted together in hot silicone oil and irradiated with ultrasonic energy to form micro/nano alloy particles. The morphology, composition and crystal structure of these particles were analyzed. It was found that bismuth forms metal matrix composites with tin and zinc, intermetallic compounds with indium and an alloy with gallium. We also followed the structural changes in the system by X-ray diffraction (XRD), differential scanning calorimetry (DSC), and electron microscopy.
