Self-adaptive dislocation morphing ductilizes a refractory high-entropy alloy across an ultrawide temperature spectrum

Proceedings of the National Academy of Sciences, Volume 123, Issue 1, January 2026. <br/>SignificanceRefractory alloys hold immense promise for high-temperature applications but are often limited by poor ductility. This work demonstrates in a model Nb40Ta25Ti15Hf15Zr5refractory high-entropy alloy (RHEA) that self-adaptive dislocation …
