Abstract

The kinetics of point defect-dislocation interactions following pulsed neutron and electron irradiations have been studied in high purity copper. In all experiments, data showed a very rapid increase in the modulus defect followed by a more gradual change. The magnitude of the rapid change in the modulus defect was proportional to the fluence. The initial rapid rise was too fast to allow for kinetics analysis; however, the slower continuous process was analyzed. Results are interpreted in terms of a model wherein interstitials are rapidly depleted and responsible for the initial rapid increase; the lower process is due to vacancy diffusion and arrival at dislocations.
