In previous articles, we have attempted to describe the global dynamics of an attritor and a SPEX mill, two devices commonly used for mechanical alloying (MA). In this, the last of this series, we compare and contrast these devices with respect to a number of features. These include alloying kinetics and the properties, scale, and structure of processed powder. In addition, we illustrate how a "local" description of MA is useful in examining the interaction between material properties and process parameters, the latter of which is often imposed by the characteristics of the device used to achieve MA.
