Abstract

The implantation of argon ions in a grade 1420 aluminum alloy is studied. The optimum mode allowing the maximum alloy softening is shown to be Е = 36 keV, j = 300 μA/cm2, and Φ = 4.9 × 1017 cm–2 (irradiation time of 7 min). An increase in the ion current density by a factor of 1.5 (up to 450 μA/cm2) causes about a twofold reduction of the irradiation time, while maintaining near the same softening level, namely, σu = 351 MPa, σ0.2 = 161 MPa, and δ = 19.8%, at a lower fluence of 3.7 × 1017 cm–2.
