对于尺寸小于1μm的细金属粉末的需求不断增加，用于催化剂，烧结助剂，磁性磁带，磁性流体，推进剂/爆炸物添加剂，微波吸收，电池和电子应用等一系列应用。伯明翰大学最近的研究导致了一种简单而灵活的元素、合金和复合材料纳米粉末加工方法的发展。利用透射电子显微镜（TEM）对其粒度、形貌和分布进行了表征。采用差示扫描量热法（DSC）和振动样品磁强计（VSM）分别研究了纳米粉体的氧化行为和磁性能。本文重点介绍了用该方法制备的纳米Al， Fe, Ni， Cu和TiN粉末的微观结构和性能。
There is an increasing demand for fine metal powders with sizes below 1μm for a range of applications including catalysts, sintering aids, magnetic recording tapes, magnetic fluid, additives for propellants/explosives, microwave absorption, batteries and electronic applications. Recent research at University of Birmingham has led to the development of a simple and flexible processing method of nanosized powders of elemental, alloy and compound materials. Their particle size, morphology and distribution have been characterised using transmission electron microscopy (TEM). The oxidation behaviour and the magnetic properties of the nanosized powders have been studied using differential scanning calorimetry (DSC) and vibrating sample magnetometer (VSM), respectively. This paper highlights the microstructure and properties of the nanosized Al, Fe, Ni, Cu and TiN powders produced by this simple method.
