Effect of high energy ion implantation on the structure and mechanical properties of aluminium alloys

Abstract

The effect of implantation of Ne+, Kr+, and Bi+ ions over the energy range 26-710 MeV on the structural-phase state and the mechanical properties of the aluminum-based alloys (Al-Cu, Al-Cu-Mg, Al-Cu-Zn, Al-Mn) was studied. The revealed peculiarities of variations in the structure, phase composition, and mechanical properties of aluminum alloys are attributed to the electron deceleration of ions making the principal contribution to the formation of radiation defects which enhance the diffusion processes in the targets.
