Description
Jie Qi and five colleagues design a new family of alloys that stay both very strong and bendable at extreme heat, in a 2024 study. Refractory high-entropy alloys suit hot structures, but their huge recipe space makes phase control and ductility hard to win together.
The team screened recipes with machine learning, atomistic simulation, and quantum calculations in one loop. The winning aluminum-rich alloys formed a single ordered phase. They reached compressive yield strengths up to 1.7 gigapascals, bent past fifty percent strain before breaking, and kept strength when hot. In tension they still yielded at a gigapascal. The authors also map which electron counts spell ductile versus brittle behavior.
