c. suryanarayana. mechanical alloying and milling, orlando, 2003, pp 2-3 . processes . mechanical milling/disordering . mechanical alloying is the generic term for processing of metal powders in high mills. however, depending on the state of the starting powder mix and the processing steps involved, it describes the process when mixtures of
milling in a planetary ball mill on its parameters. kakuk et al. 2009 modelled the milling process in a planetary ball mill and found a relationship between the angular velocity of the sundisk and the vials, and the geometrical parameters of the mill. farahbakhsh et al. 2011 investigated the mechanical alloying of
mechanical alloying ma is a solid-state and powder processing technique involving repeated cold welding, fracturing, and re-welding of blended powder particles in a high-energy ball mill to produce a homogeneous material. 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

nano ball milling 1. ball milling method by aravind n. b 2. nano materials can be defined as those materials which have structured components with size less than 100nm at least in one dimension. nanotechnology is an advanced technology, which deals with the synthesis of nano-particles, processing of the nano materials and their applications.
mechanical milling is a high-energy ball milling process in which, constituent powders are repeatedly deformed, fractured and welded by grinding media to form a homogeneous alloyed microstructure
the crystallite size decreases with milling time up to 40 h of milling. the variation of lattice strain induced by milling based on voigt function analysis has shown in fig.16 a . the strain increases as the milling time increases. through ball milling, mechanical energy is pumped into the al 70 co 15 ni 15 matrix. a part of the energy is used
