摘要：

Impact of milling balls is believed to play a significant role in the mechanical alloying (MA) process. It is therefore important to analyze the motion of milling balls during ball milling to clarify the effect of impact energy upon the MA process. In this study, the motion of balls in a one-dimensional vibratory mill was analyzed by means of model simulation, taking into account the energy consumption during impact of balls. In addition, a milling experiment on a mixture of copper and graphite powders was conducted by a conventional vibratory mill. It was found that the microhardness of the powder particles milled for a long period is related to the average impact energy calculated by the model simulation. The rate of shape change during milling was also found to be dependent on the calculated impact frequency. © 1990, The Japan Institute of Metals. All rights reserved.
