Abstract

The synthesis of aluminium (Al) nanocrystalline powder by high-energy ball milling has been investigated. Al powders were ball milled in an argon inert atmosphere. The milled powders were characterized by X-ray diffraction and scanning electron microscopy measurements. The high-energy ball milling of Al after 12 hours resulted in crystallite size (particle size) of about 76 nm. Particle size and lattice strain in Al powder produced by milling have been analyzed by X-ray powder diffraction. The lattice strain () and Debye-Waller factor (B) are determined from the half-widths and integrated intensities of the Bragg reflections. In this Al, the Debye-Waller factor is found to increase with the lattice strain. From the correlation between the strain and effective Debye-Waller factor, the Debye-Waller factors for zero strain have been estimated for Al. The variation of energy of vacancy formation as a function of lattice strain has been studied.
