| Abstract Scope |
High-entropy alloys (HEAs) are a class of multi-principal element alloys with high configurational entropy and severe lattice distortion. The radical departure from the conventional design motif has shifted the alloy design space from the corners of a phase diagram to the more spacious central region, which opens a new arena for explorations of new materials with new properties. Towards the widespread application of HEAs, the ability to manufacture them into geometrically-flexible components is necessary. Currently, HEAs are mainly processed by casting. Unfortunately, the highly concentrated HEA solid solutions often demonstrate a large solidification range that causes the inferior castability. To address this limitation, I will present some recent work in our group on additive manufacturing of HEAs, which enables the access of engineered hierarchical microstructures with excellent mechanical properties.
