Abstract
The hardness of high purity copper has been increased through Equal Angular Channel Pressing method. The application of ECAP method with extrution rute Bc , in which the sample was rotated 90° for each pass, result in the generation of sub-grain within the grain. The size of new grain (sub –grain) is drastically smaller than initial grain and also has low angle. With the decreasing of grain size, the hardness drastically increases.
