UrduScientists have measured the highest toughness ever recorded, of any material, while investigating a metallic alloy made of chromium, cobalt, and nickel. Not only is the metal exceptionally strong and ductile, its properties become enhanced as it gets colder. This runs counter to most other materials in existence.

Scientists shed light on 140-year-old challenge in chemistry and physics
In recent research published in the Proceedings of the National Academy of Sciences, Lawrence Livermore National Laboratory (LLNL) researchers Babak Sadigh, Luis Zepeda-Ruiz and Jon Belof report on a new mechanism of solidification in copper that provides an atomistic view of Ostwald’s step rule and alters the fundamental understanding of nucleation at high pressure. They found that not only does the crystallization process proceed via a non-equilibrium phase, but that this phase can be kinetically stabilized by the temperature.
LLNL teams solves 100-year-old metallurgy puzzle
To solve a 100-year puzzle in metallurgy about why single crystals show staged hardening while others don’t, Lawrence Livermore National Laboratory (LLNL) scientists took it down to the atomistic level.
