High entropy alloys with predictable mechanical properties by computational modelling - HEAMODELL

Project summary

High entropy alloys (HEA) are recently developed metallic materials, composed of five or more principal elements, which feature high mechanical and oxidation resistance properties at elevated temperatures. The complexity of HEA inherent to the large number of possible elemental combinations represents a serious challenge for industrial implementation. HEAMODELL project is proposing to establish new thermodynamic and kinetic criteria based on composition-solidification-heat treatment-structure correlations, making use of electronic, atomistic and macro-scale modelling techniques, coupled with a focused experimental and characterisation approach. The integrated multiscale model for HEA design is validated at laboratory level including alloy synthesis/processing at pilot scale. Project results will contribute to the improvement of ICME predictive power for high temperature alloys for jet engines and to shorter time-to-market for innovative materials with high market impact.
