We herein exploit the advantages of surfactant assisted-high energy ball milling (SA-HEBM) for the processing of Mn–Al alloy. In this method, a combination of two surfactants, such as oleic acid and oleylamine, was used along with a solvent, n-heptane, during milling.The use of the SA-HEBM process yielded two different products: a sediment powder consisting of sub-micron sized Mn–Al flakes ...
route is described as high energy ball milling (HEM). The definition of Reactive Milling (RM) is suitable if during milling a chemical reaction is wanted and observed. The advantage here can be an ultra-fine dispersion of particles in a matrix (e.g. Ag-SnO2 where the starting powder is AgO2 + Ag3Sn) [5]. The following table 1 gives most important applications of High Energy Milling, Mechanical ...
