Two experimental alloys resisted cracking at −424°F by forming new crystal defects, offering a possible route to tougher metals for extreme cold. Most metals become stronger as they cool, but some also become more vulnerable to breaking. Iron, tungsten, and chromium belong to a class called body-centered cubic metals, whose atomic arrangement can make them […]
