| Abstract Scope |
Despite extensive progress in high-entropy alloy (HEA) discovery, a persistent gap remains between thermodynamically predicted compositions and experimentally manufacturable alloys. Most design strategies emphasize equilibrium phase stability while implicitly assuming synthesizability, leading to a proliferation of candidate HEAs that are difficult to fabricate or scale. In this work, we address this gap by introducing a manufacturability-aware alloy design framework that derives quinary equiatomic HEAs directly from conventional alloy chemistries with established metallurgical compatibility. The framework integrates classical thermodynamic descriptors with physically motivated constraints governing co-melting behavior, atomic solubility, and elemental volatility—parameters that critically influence solidification and phase selection during fusion-based processing. Application of the approach across multiple industrial alloy families reveals a large, previously underexplored design space of quinary HEAs with high likelihood of single-phase stability and practical processability. Detailed design rational and experimental results will be discussed at the conference. |
