ball milling conditions to reduce ash

Apr 15, 2019· 1. Introduction. Mechanical alloying (MA) is a well-known way in processing advanced materials involving repeated welding and fracturing the powder particles in a high energyball mill[1,2].First developed by Benjamin and his co-workers in 1970s [3,4], this processing method has been shown the potential in synthesizing supersaturated solid solutions, amorphous alloys, nano-crystalline ...

    Ballhardness is in the 60–67 HRC range. They wear better than 440C stainless steel and through-hardened carbon steel. They are also recommended for applications where a through-hardened steelballis needed in larger sizes (½" and larger). They are sometimes packaged with a very light oil finishto reducerust due to humidity.
