“…Grain boundary embrittlement in precipitate hardened alloys such as PE16 have been attributed to one or a mix of several mechanisms; radiation-induced hardening and the limited permissible relief of triple point stresses due to grain boundary sliding, 64 brittle failure of radiation-induced continuous grain boundary films of gamma prime (or eta phase in the case of Alloy 706) and grain boundary helium bubbles. 65,66 However, Boothby 67 emphasises that any radiation-induced formation of continuous intergranular eta or gamma prime films are strongly dependent on the initial alloy condition; with such films only observed in solution-treated materials and not in fully aged material. Further to this, grain boundary embrittlement of PE16 has been observed both with and without irradiation-induced intergranular gamma prime, with the dominant embrittlement mechanism being most likely related to intergranular helium bubbles.…”

The effects of neutron radiation on nickel-based alloys in thermal reactors are defying predictions that were made based upon accelerated testing in fast reactors. As nickel-based alloy components face significant doses in aging thermal reactors and their role in Gen-IV reactor designs becomes prominent, the literature on the effects of radiation on such alloys must be reviewed to enable better structural integrity assessments for relevant components and optimise alloys with respect to irradiation embrittlement resistance. This paper reviews the available data on the effects of radiation, notably neutron radiation, on nickel-based alloys and discusses the possible mitigation strategies and design opportunities for radiation embrittlement-resistant alloys based on recent developments in alloy computational design. This review was submitted as part of the 2016 Materials Literature Review Prize of the Institute of Materials, Minerals and Mining run by the Editorial Board of MST.
