摘要: A model of high-energy ball milling powders has been proposed. It is demonstrated that part the energy consumed for initiation microstrains e during and, hence, process powder grinding decelerated. An analytical expression deduced describing size nanocrystalline particles as a function time. The and experiment have compared, using tungsten carbide (WC). average value in ball-milled were determined by an x-ray method from broadening diffraction reflections. was also evaluated scanning electron microscopy sedimentation method.
