later termed "mechanical alloying" by Ewan C. Mac-Queen, a patent attorney for INCO. The formation of an amorphous phase by mechanical grinding of a Y-Co intermetallic compound in 1981 [21] and in the Ni-Nb system by ball milling of blended elemental mixtures in 1983 [22] established MA as a .
Feb 02, 2016· Mechanical alloying in a continuous action planetary ball mill, PCM-50-nano. ... How To Make a Ball Mill 2 - A High Energy Ball Mill - Duration: 10:18.
5.2 Fundamentals of mechanical alloying processes in ball mills. A ball mill is a relatively simple apparatus in which the motion of the reactor, or of a part of it, induces a series of collisions of balls with each other and with the reactor walls (Suryanarayana, 2001).
In a review of Suryanarayana and Al-Aqeeli (2013) it is reported that only 15% of the studies used stirred media mill for mechanical alloying and 80% utilized mainly planetary ball mill or shaker mill and further 5% other mill types. Furthermore, among the 15% stirred media mills most of them are low velocity vertical attritors and not high ...
