Scientists discover metals that defy the deep freeze at -424°F

Scientists have discovered a surprising mechanism that allows certain metals to resist cracking at temperatures as low as -253°C (-424°F), when similar materials typically become dangerously brittle. Instead of breaking, two experimental alloys reorganize their internal structure
