World-first 'super alloy' is 2x as strong as steel

Australian engineers at Monash University created the world's first large piece of Refractory High-Entropy Alloy (RHEA), a material twice as strong as steel with a compressive yield strength exceeding 2 gigapascals. Using lower temperatures than traditional methods, atoms self-organized into a defect-free, ductile structure — a breakthrough that could make alloy production cheaper and more scalable, with potential applications in aerospace, energy, and advanced manufacturing.
