چکیده انگلیسی
The effects of plastic deformation by ball milling on the structure of a partly amorphous Al87Ni8La5 alloy were investigated by X-ray diffractometry. Lattice parameter, crystallite size and lattice strain of the fcc-Al precipitates were determined by Rietveld refinement, double-Voigt approach and Williamson-Hall plots. The changes in lattice parameter of fcc-Al nanoprecipitates during ball milling are ascribed to the uptake of Ni. The crystallite size decreases as a function of the milling time from about 100Â nm in the as-atomized state to about 14Â nm after 1440Â min of ball milling time. A model based on shear deformation of precipitates in the amorphous phase is used to describe quantitatively the decrease in crystallite size and change in lattice parameter.
