ORDERING THROUGH VACANCIES, INTERSTITIALS AND CROWDIONS IN FCC ALLOYS
In fcc metals and alloys, recovery stages III after irradiations with high energy particles and recovery stages IV after quenching are found to be well separated with respect to the temperature ranges as well as with respect to the respective activation energies. In alloys showing short range order, recovery stages IV are also found after irradiations. In such alloys, one can distinguish between one- and three-dimensionally migrating defects, namely crowdions and interstitials, respectively, because crowdions cannot enhance diffusion but thermally activated crowdions, e.g. crowdion - vacancy pairs of stage I-D, can nearly restore the degree of short range order existing prior to irradiation.
