Effect of energy parameters of ball milling on microstructure of Cu nanostructured powder

Résumé

The microstructure evolution of Cu nanostructured powders at different conditions of the ball milling is investigated by the x-ray diffraction analysis. The characteristics of as-milled Cu-powder microstructure in terms of crystallite sizes, type, and density of dislocations as well as twin-faults' density are determined by the whole peak-profiles' modelling of powder x-ray diffraction pattern. By comparing of both microstructure characteristics of Cu powder and the ball milling parameters, the dominant factors of ball milling, which affect on the concentration of twin faults, type, and density of dislocations as well as the size of crystallites, are revealed.
