Effect of ion irradiation on the resource characteristics of alloy V95 (Al – Zn – Mg – Cu)

Abstract

The study of the effect of irradiation with Ar+ ions with an energy of 20 keV, ion current density j = 200 μA/cm2 on the fatigue resistance of profiles 6 mm thick made of alloy V95 (Al – Zn – Mg – Cu) in the state of delivery: after hot pressing, quenching and artificial aging, has been carried out. It was found that irradiation with Ar+ ions fluence of 1·1016 cm–2 to an increase fatigue resistance in 6.4 times under conditions of reduced load amplitudes σ/σu = 0.3.
