Design and optimization of 3D printable oxide-dispersion-strengthened multi-principal element alloys for extreme environments

Anotace

The future of sustainable development of human society directly depends on improvement in energetic and economic efficiency. Such advancement in electric power generation or propulsion requires discovery and development of high-performance materials. Following-up our recent revolutionary work (Nature, 2023) the goal is to explore a newly opened compositional space for design and optimization of cost-effective and sustainable 3D printable oxide-dispersion-strengthened multi-principal element alloys (ODS-MPEAs). The predictive power of thermodynamic calculations will be combined with rapid alloy production by additive manufacturing. Promising candidate materials will undergo accelerated mechanical testing in terms of monotonic load, creep and fatigue. Complemented by state-of-the-art multi-scale characterization and supported by the atomistic simulations, the key design aspects determining alloy performance will be assessed. Proposed multi-layered optimization approach will result in the development of new 3D printable ODS-MPEAs for use in the targeted temperature range of 800-1000°C.
