Scientists discover high-strength, temperature-resistant metal alloy for advanced engines.

Researchers at Berkeley Lab and UC Berkeley, along with UC Irvine and Texas A&M University, have discovered a metal alloy made of niobium, tantalum, titanium, and hafnium that boasts impressive strength and toughness at extremely hot and cold temperatures. This unique combination of properties could pave the way for a new class of materials for high-efficiency next-generation engines.
