Hardening of SS316 Stainless Steel Caused by the Irradiation with Argon Ions

Hardening of SS316 Stainless Steel Caused by the Irradiation with Argon Ions

We study the correlation between the radiation-induced hardening and the evolution of microstructure of SS316 stainless steel irradiated with 1.4 MeV Ar + ions within the dose range 0–25 dpa at 300 and 900°K. It is shown that the degree of hardening attained under these doses can be as high as 75% a...

Zusammenfassung:We study the correlation between the radiation-induced hardening and the evolution of microstructure of SS316 stainless steel irradiated with 1.4 MeV Ar + ions within the dose range 0–25 dpa at 300 and 900°K. It is shown that the degree of hardening attained under these doses can be as high as 75% and its saturation is observed at 2 dpa. The clusters of defects and dislocation loops with sizes smaller than 15 nm make the principal contribution to the radiation-induced hardening.
