RADIATION EFFECTS UPON AND RECOVERY OF THE MECHANICAL PROPERTIES OF METALS

摘要

The experimental data on the production and recovery of irradiationinduced, mechanical-property change in metals are reviewed. Damage is interpreted as a two-stage process involving source hardening and lattice hardening, caused by clustered interstitials or vacancy clusters. Annealing entails migration of polyvacancies or dissipation of vacancy clusters, and requires the activation energy of self-diffusion. A recovery parameter, Q/T, is defined.
