Investigation of the Effect of Implantation of Aluminum Alloys by Gas and Metal Ions on the Structure and Phase Composition of the Implanted Layer

Abstract:

The article presents studies of the structure and phase composition of aluminum alloys after ion implantation. It is shown that the effect of accelerated ions (Cu + Pb) (E = 30 keV, j = 100 μA / cm²) on an alloy without a cladding layer already at a dose of 10¹⁶ cm ^{- 2} leads to the formation of a developed subgrain structure in the initially deformed alloy. With an increase in the ion current density and radiation dose, the cellular structure of the implanted aluminum alloys becomes more regular - well-formed cells are observed practically throughout the entire volume of the sample under study. The average width of the dislocation-free regions reaches 2.5 μm with the width of the boundaries not exceeding 0.6 μm.
