OAK RIDGE, TN—Scientists have measured the highest toughness ever recorded, of any material, while investigating a metallic alloy made of chromium, cobalt and nickel (CrCoNi). Not only is the metal extremely ductile and impressively strong, its strength and ductility improve as it gets colder. This runs counter to most other materials in existence.
The team, led by researchers from Lawrence Berkeley National Laboratory and Oak Ridge National Laboratory, published a study describing their record-breaking findings in Science on Dec. 2, 2022.
