    Low-energy ball-milling: Transformations of boron

    Abstract. BN powders (with and without water) which have undergone low-energyball-milling have been studied through X-ray diffraction,transmission electron microscopy, granulometry, electron energy loss (EELS) and IR spectroscopies. The main result is the formation of theorthorhombic and cubic high pressure phases of BN

    Jun 04, 1998 ABSTRACT The influence of low energy ball milling on the crystallite size, lattice strain, and storage of deformation energies of elemental metal powders is studied. The formation of nanosized grains (5–25 nm) and enhancement of lattice strain up to 0.4% is found. Excess enthalpies of up to 25% of the heat of fusion are reached. REFERENCES 1. J. S
