Reduction of vacancy concentration during storage of severely deformed Cu

Reduction of vacancy concentration during storage of severely deformed Cu

A reduction of the stored energy in Cu processed by equal-channel angular pressing was observed after 4 years of storage at room temperature. It was found that the decrease of stored energy was most probably caused by the loss of excess vacancies.
