| Abstract Scope |
High entropy alloys (HEAs) are of interest for a number of industrial applications, including the atomic energy sector, due to their potentially beneficial radiation damage tolerance. These properties are often linked to the set of founding principles, established when the materials were first conceived. However, over recent years research into HEAs has started to challenge these founding principles, bringing into question the root cause of the unique and sometimes exceptional properties. In particular, it is now believed that there are several local structural features that contribute to these unique behaviours.
In this talk, we will discuss the elucidation of local structure within several HEA systems with ranging compositional complexity (from ternary to quinary), conceived for nuclear fusion applications. Neutron total scattering data, obtained at the ISIS Neutron source, is analysed using a combination of small and large box modelling and used to provide a local structural probe of the system. |
