| 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. In particular, the MPEAs containing refractory elements, offer the potential for high-temperature structural applications. However, knowledge of the phases that exist and develop within these compositionally complex spaces is still limited.
In this talk, we will discuss how machine learning (ML) models, built on thermodynamic databases, have been used to explore the BCC MPEA refractory containing space and predict single phase materials. Promising materials have been manufactured and their phase structures and compositions assessed through SEM:EDX and a combination of variable temperature X-ray and Neutron scattering data. Knowledge of the phase formation will help inform and guide future thermodynamic modelling and phase-space predictions, improving future alloy design. |
