Mechanical alloying and milling - ScienceDirect
Recent developments in understanding the process of mechanical alloying through modeling and milling maps is briefly described in Section 15. The applications of mechanically alloyed products are described in Section 16 and the problem of safety hazards in handling fine powders such as those produced by mechanical alloying are discussed in Section 17 .
Ball mill - Wikipedia
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati
Mechanical alloying - Wikipedia
Mechanical alloying (MA) is a solid-state and powder processing technique involving repeated cold welding, fracturing, and re-welding of blended powder particles in a high-energy ball mill to produce a homogeneous material. Originally developed to produce oxide-dispersion strengthened (ODS) nickel- and iron-base superalloys for applications in the aerospace industry, MA has now been shown to ...
