Аннотация

The microstructure evolution of Cu-nanostructured powders versus the ball milling conditions was investigated using X-ray diffraction analysis. The characteristics of as-milled Cu powder microstructure in terms of crystallite size, dislocations and twin boundary densities were determined by fitting the simulated X-ray diffraction peak profiles to the experimental ones in order to establish a correlation between the powder microstructure and the ball milling parameters. It was shown that the simulated X-ray diffraction peak profiles agree satisfactorily with the experimental ones taking into account transmission electronic microscopy observations where twin boundaries and dislocations were observed.
