Abstract:Based on the estimation method of mixture ratio of covered composite particles presented by ALONSO and two existing forms of nanometer particles in composite powders, a theoretical model of mixture ratio of micro/nano-powders prepared by mechanical composite process is established by theoretical analysis. The mixture ratio determination of D-ratio of grain size powders was, then discussed the filling coefficient through experiments was identified, and the theoretical estimation results were compared with correlative experimental ones. The result shows that the model formed has good operational performance. The model is only related to the densities of microns and nanometer powders, when the ratio of grain size is 3 and more than 3 orders of magnitude.It is indicated that the estimation results are consistent with the experimental optimal ones. This is confirmed that the model discussed has considerable application prospect and reference value for micro/nano-powders prepared by mechanical composite process.
