SURFACTANT-ASSISTED BALL MILLING: A NOVEL ROUTE TO …
Ball milling is a powerful non-equilibrium process-ing method capable of producing dispersion strength-ened alloys with fine microstructures as well as metastable structured materials [16]. The milling process, which can be either (1) mechanical milling or (2) mechanical alloying, refines the grain size of all solid elements into nanoscale [17,3].

Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.
