摘　　要：利用Benjaminm碰撞模型推导出高能研磨制备片状铝粉研磨过程中研磨时间与粉体片厚和片状铝粉中位径D50的关系方程式，研究结果表明，研磨时间与纳米粉体片厚呈反比关系，与粉体的平均粒度D50呈正比关系。用该模型计算的片厚与D50跟实验值吻合较好。该模型也可推广应用到高能球磨制备其他纳米片状金属及合金粉体，以及用于指导工业生产和优化工艺。Deduced the equation of the relations between the milling time, thickness, and medium particle size D50 of Al-flakes of high-energy Milling （HEM） by Benjaminm collision model. The results showed the milling time was inversely proportional to the thickness of the Al-flakes and was directly proportional to the D50 The thickness and the D50 fitted the calculate value of the model and measure value. This kind of model also could be used to nano-metal flakes and alloy in the high-energy Milling, and the guidance of industrial manufacture and optimize the process.
