Researchers say a new refractory high-entropy alloy made from hafnium, niobium, tantalum, titanium, and zirconium reached more than twice the strength of steel while staying ductile. The approach uses lower-temperature, controlled heating to encourage atoms to self-organize into a more ordered, defect-free structure, which could inform future alloy design for aerospace, energy, and other industries.
