Dislocation loop growth and void swelling in bounded media by charged particle damage. [4 MeV nickel ions

Abstract

A system of partial differential rate equations for the growth of dislocation loops and voids in one-dimensionally bounded media, namely the semi-infinite medium and the foil, under charged particle irradiation has been formulated in terms of the diffusion controlled kinetics of defect annealing and cluster growth. An efficient numerical method of integrating the rate equations is presented. Example calculations for 4 MeV Ni self-ion bombardment at 550/sup 0/C are made, and both time and space dependences of loop growth and void swelling are discussed.
