Investigation of the influence of ion-implanted surface layer on the development of plastic deformation of polycrystalline aluminum at the mesolevel

Research output: Contribution to journalArticle

Abstract

The effect of the thin surface layer modified by ion implantation on the development of plastic deformation of polycrystalline technical grade aluminum at the mesolevel has been studied by a high-resolution television-optical complex. Ion implantation was performed on a DIANA-2 ion implanter. Nickel ions with an average energy of 90 keV were implanted to irradiation fluences 1×1017 and 5×1017 ion×cm-2. Metallographic study of lateral faces of implanted specimens has shown that the development of deformation in the near-surface layer approximately 200-250 μm thick at the initial stages of deformation (ε≤10%) occurs more homogeneously than in the bulk of the main specimen. It has been found that the difference in mechanical properties of the surface layer doped during ion implantation and of the matrix material results in the formation of a periodical structure of the deformation relief which appeared in the pattern of displacement vectors as a spatial `wave' with the length approximately 400 μm. The maximum effect has been observed at the radiation fluence of 1×1017 ion×cm-2.
