Dramatic reduction of void swelling by helium in ion-irradiated high purity α-iron [PDF]
Materials Research Letters, 2018 Effect of helium on void swelling was studied in high-purity α-iron, irradiated using energetic self-ions to 157 displacements per atom (dpa) at 773 K, with and without helium co-implantation up to 17 atomic parts-per-million (appm) He/dpa.

Study of Helium Swelling in Nitride Ceramics at Different Irradiation Temperatures [PDF]
Materials, 2019 This paper presents the results of a systematic study of helium swelling and the subsequent process of degradation of the near-surface layer of aluminum-based nitride ceramics. The samples were irradiated with 40 keV He2+ ions at temperatures of 300 and 1000 K with a fluence of 1 × 1017–5 × 1017 ions/cm2.
