ION-IMPLANTATION AND LONG-RANGE INTERACTION EFFECT IN POLYCRYSTALLINE, ALPHA-FE

The results of electron microscopy studies of the ''long-range interac tion'' effect in ion-implanted alpha-Fe are presented. Ions of C, Fe, W, Hf and Ar were implanted in continuous and repetitive pulse modes. Ion energy varied in the range 40 to 110 keV radiation dose varied fro m 1.10(16) to 1.10(18) ion.cm(.2). A developed dislocation structure w as formed in the 20-100 mu m thick near-surface layer, whereas the pat h length of ions in alpha-Fe does not exceed 50 nm The causes of the a ppearance of the dislocation structure on ion implantation an analyzed .
