- Scientists developed a new alloy manufacturing method using lower, controlled temperatures and specific 'baking' times to create metals stronger than current materials.
- The process involves mixing hafnium, niobium, tantalum, titanium, and zirconium, followed by high-temperature melting and prolonged heating at 550°C, resulting in a Refractory High-Entropy Alloy (RHEAD).
- This new alloy is twice as strong as steel, three times stronger than aluminum, and twice as strong as conventionally made versions, with high compressive yield strength and retained ductility.
- The key improvement comes from atoms self-organizing into smaller, well-packed, defect-free grain structures, offering enhanced stability and strength without increasing alloy content.
