This research focuses on developing and characterizing high-temperature high-entropy alloys (HT-HEAs) using powder-based additive manufacturing techniques, including directed energy deposition (DED) and powder bed fusion (PBF). By utilizing mixed powders, including pre-alloyed and elemental compositions, the study aims to explore flexible and efficient methods for alloy design tailored to high-temperature applications. The project investigates the influence of processing parameters and heat treatments on the microstructure, thermal behaviour, and mechanical properties of these advanced alloys.
A multi-scale characterization approach, including scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and mechanical testing, is employed to assess the alloys’ performance and functional properties. The results aim to advance the understanding of process-structure-property relationships in HT-HEAs and highlight the potential of mixed-powder strategies in accelerating alloy development through additive manufacturing.
