| Abstract Scope |
This lecture will discuss recent work at Sydney on the measurement of short range order (SRO) and its phenomenological implications in materials science. Our scattering-based approach to determine pair distribution functions will be discussed, emphasising the significance of accurate background subtraction and elliptical distortion. The interoperability of our approach between different diffraction intensity profiles will be explained. Our non-scattering approach using atom probe tomography (APT) will be presented, and our sensitivity analysis that describes clear regimes where the measurement of species-specific SRO is viable using APT will be summarised. Finally, our reason for seeking to quantify these aspects of solid solutions will be discussed, since the phenomenology of clustering-type SRO enables the tuning of mechanical and functional properties of materials. Examples will be presented across aluminium alloys, metallic glasses and high entropy alloys, some of which have translated into industrial materials engineering practice. |
