Milling media, milling time, ball to powder ratio, milling speed, and starting powder size range influence both the stages of milling and the quality of milled product [14–16]. MA and MM in different milling media result in changing of powder properties and consequently alter mechanical, physical, and thermal properties of the final products.
More then a decade ago, high-energy ball milling of powder mixtures, were reported to be efficient techniques for the preparation of nanocrystal- line metals and alloys [2—4]. Indeed, as mechanical processing tech- nique [5], ball milling is effective for the production of micrometer size particles composed of nanosize grains [6—9].
