| Abstract Scope |
Multi-Principal Element Alloys (MPEAs) are of interest for a number of industrial applications, including the atomic energy sector, due to their potentially beneficial radiation damage tolerance properties. The cause of these favourable properties has been the topic of discussion for many years with recent hypotheses suggest that local structural effects within these alloys may cause of the unique properties displayed.
In this talk, we will discuss the elucidation of local structure within several MPEA systems, conceived for nuclear fusion applications. Their phase structures and compositions are assessed through SEM:EDX. Neutron total scattering data was obtained at the ISIS Neutron source on a series of increasing compositionally complex samples to cryogenic temperatures. Pair Distribution Functions (PDF), obtained from these data are analysed using a combination of small and large box modelling and to provide insight into the local structural nature of the system. |
