| Abstract Scope |
Growth nanotwins (NT) are a promising microstructural feature associated with enhanced strength and thermal stability in nanocrystalline materials. To date, research on nanotwinned materials has been limited to single and binary element systems due to the lack of stacking fault energy (SFE) values and the high time costs associated with exploring broader compositional spaces. In this work, a combinatorial high-throughput (CHT) methodology is employed to investigate the processing-microstructure relationship driving NT formation in binary NiCr and NiFe alloys, which serve as precursors for Inconel 725. Regions where NT formation is either promoted or inhibited were identified, with Cr additions promoting a more densely and finely spaced NT microstructure than Fe. Attributed to the dependence of stacking fault energies on composition, this study demonstrates that a CHT approach can be leveraged to fundamentally understand growth twinning domains. |
