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

2006

International audience; 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.

Correlation between milling parameters and microstructure characteristics of nanocrystalline copper powder prepared via a high energy planetary ball …

2007

The microstructure evolution of Cu-nanostructured powders versus the ball milling conditions was investigated by whole peak profile powder pattern modeling method. This method allows defining in some approach the characteristics of as-milled Cu powder microstructure in terms of crystallite size, type and density of dislocations and twin faults density. It is shown that the change of microstructure characteristics of as-milled Cu powder versus the ball milling conditions (under constant time of the ball milling) depend on only some energy parameters of the milling, for example, average size of crystallite is uniquely defined by energy of the shock, whereas the portion of edge and screw compo…
