The anomalous specific heat due to recovery from strain hardening has been measured on the single crystals of copper deformed at various temperatures. The apparatus for specific heat measurement is that of Nagasaki and Takagi. (1) The maximum value of the energy stored during deformation at room temperature is found to be 0.1 cal per gram. (2) The energy released in the second valley of the specific heat anomaly (the energy accompanied with stopped dislocations) shows rapid increase when the resolved strain exceeds 25 percent. (3) The recoverying temperature takes the maximum value when the resolved strain is about 25 percent. (4) The crystals deformed at - 180℃ and - 80℃ recover sometimes below the room temperature. Results of (3) and (4) may be explained by taking account of the length of dislocation lines. (5) The density of dislocations is calculated from the dependency of recoverying rate upon the degree of hardening. The obtained value of the separation distance of dislocations is about 200 Å and shows good agreement with the results obtained by electron microscope.
