摘要

The effect of pulsed ion-plasma irradiation in the Plasma Focus Vikhr setup and irradiation with 20-MeV electrons at the Microtron-ST accelerator on the mechanical properties of the Inconel 718 precipitation-hardened alloy obtained by the selective laser fusion method has been studied. It was found that ion-plasma and electron irradiation does not affect the properties of the alloy, which is explained by the small thickness of the modified layer during irradiation at the Plasma Focus setup and insufficiently high electron fluence for the manifestation of radiation-stimulated process of redistribution and dissolution of dispersed precipitates of the strengthening phases. The results obtained bear evidence of a high resistance to crack propagation and the absence of a tendency of the studied alloy to embrittlement.
