Preparation of nanocrystalline copper by hot and cold compaction : Characterization of mechanical and electrochemical properties

Mechanical alloying has been used to produce nanocrystalline copper. Data on mechanical and electrochemical of nanocrystalline materials have been limited by the difficulty in producing nanocrystalline materials for characterization and evaluation. The results of the given study show that the densification of compacts nc-Cu depends on the temperature and the pressure. An enhancement of resistance corrosion of nc-Cu compacts have been observed.
