Researchers Create Metal Alloys Resilient to Extreme Temperatures

Scientists at Lawrence Berkeley National Laboratory have engineered novel metal alloys with body-centered cubic (BCC) atomic structures that resist fracturing at temperatures as low as 20 Kelvin (-423 degrees Fahrenheit) while maintaining integrity at high heat. This discovery challenges existing understanding of metal behavior, as many metals become brittle in extreme cold. The breakthrough has implications for advanced materials in energy systems, spacecraft, and jet engines.
