摘要
Isochronal as well as isothermal measurements have been made on high purity single crystals of iron which had been cold rolled about 10% prior to annealing. Two steps were isolated corresponding first to the annihilation of screw dislocations and then to the elimination of edge dislocations at higher temperatures. A method was developed for analyzing the isochronal annealing data to yield the activation energies. The two activation energies for edge and screw processes were small compared with the activation energy for self-diffusion. They were consistent with that for thermally activated dislocation mobility.
