Ball Mill - an overview | ScienceDirect Topics
The mill is evacuated during milling to a pressure of 10 −6 Torr, in order to avoid reactions with a gas atmosphere. [44] Subsequently, this mill is suitable for mechanical alloying of some special systems that are highly reactive with the surrounding atmosphere, such as rare earth elements.

Pure Al powders were mixed with a 30 % volume fraction of Al2O3 powders having particle sizes of ~30 nm. The mixed powders were first subjected to ball milling (BM) and thereafter consolidated by high-pressure torsion (HPT) at room temperature under a pressure of 3 GPa for 10 turns. The Al–Al2O3 composite produced by BM and HPT (BM + HPT) had a …
