Effect of high energy mechanical milling on the properties ...


The process of nanocrystalline structure formation during mechanical milling was studied in Cu powders. A detailed microstructural study of powder samples was carried out by Xray diffraction experiments as a function of milling time. As a result, nanosized powders have been synthesized with microstructures showing a significant decrease of the coherent diffraction domains and the creation of ...
