Application of mechanical alloying/milling for synthesis of - Ball Milling

Mechanical alloying (MA) and mechanical milling (MM) techniques have been widely utilised over the past two decades for synthesis of various alloys and composites with equilibrium or metastable structure at room temperature. One of the most interesting features of MA/MM is the ability to produce nanocrystalline and amorphous materials.Dry ball milling (DBM) is when a sample is subjected to the milling procedure under dry conditions. Terms such as "wet grinding", "solvent-drop grinding", "liquid assisted grinding", and "kneading" all imply that a solvent is involved, whether by intention or not (air humidity) [ 15 ].
