WEBDuring alloy formation using ballmill, two processes simultaneously occur: (a) fracturing, and (b) cold welding of powders. Thus, it becomes imperative to create a balance between these processes for successful alloying. In mechanical alloying, planetary ball mill is commonly employed because it involves very small quantities of precursor powders.
