Mechanical Alloying Of Si And Ge In A Planetary Ball Mill

Mechanical alloying (MA) is a solid-state powder processng technique involving repeated welding, fracturing, and rewelding of powder particles in a high-energy ball mill. 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 be capable of synthesizing a variety of equilibrium and non-equilibrium alloy.

The basic process of mechanical alloying is that the powder and particles of several kinds of metallic and non-metallic elements are repeatedly mixed, crashed and cold welded in ball mill, gradually refined to nano level in the process of ball milling, and form a nucleus of alloy phase in solid state, which has made some substances difficult to.

Due to the high flexibility available for selecting the grinding parameters, it is possible to achieve results unattainable with any other ball mill. This is the ideal mill for mechanical activation and alloying. The main applications are in the field of materials research and wherever a powerful, innovative planetary mill.

Further milling of the powder adhering on the wall of the jar led to a high densification of the heterogeneous cold welded layer but not to any improved mechanical alloying. Mechanical alloying only took place inside the jar where fine elemental powder particles are efficiently impacted between the moving milling balls.
