Nanoscale alloy redesign tackles cold brittleness for potential deep-space and deep-sea applications

Metallic materials used in extremely cold environments must maintain high strength, ductility and fracture toughness to support applications in aerospace, clean energy, superconducting systems and deep-space exploration. However, traditional alloys often suffer performance degradation at ultralow temperatures because of the long-standing trade-off between strength, ductility and toughness. Although metals may become…
