| Abstract Scope |
High entropy and compositionally complex alloys provide a large amount of flexibility in terms of component elements, but the single-phase alloys that largely populate this space are often limited in the strengthening mechanisms they have access to. Beyond solid solution strengthening and grain refinement, multi-phase alloys can be further tailored to optimize engineering properties. Alloys which have an FCC matrix phase, especially, may be optimized for strength and corrosion resistance while retaining a reasonable amount of ductility. By combining inspiration from existing multiphase alloys with corrosion resistance sensibilities, microstructure-based strain hardening models, and thermomechanical processing informed by phase stability predictions from ThermoCalc, a novel steel or other lightweight alloy strengthened by an ordered second phase may be designed which has exceptional performance in marine environments. |
