摘要

研究了能量为20 keV、离子电流密度j = 200 μA/cm2的Ar+离子辐照V95 (Al - Zn - Mg - Cu)合金6 mm厚型材经热压、淬火和人工时效后，在交付状态下的抗疲劳性能。结果表明，在减小载荷幅值σ/σu = 0.3的情况下，辐照辐照辐照辐照后，合金的抗疲劳性能提高了6.4倍。

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

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.
