Researchers have uncovered a new remarkable metal alloy that doesn’t crack at extreme temperatures due to kinking, or bending, of crystals in the alloy at the atomic level. 

Unlike most materials, the new alloy displays impressive strength and toughness at extremely hot and cold temperatures, a combination that seemed nearly impossible to achieve until now.

Researchers say the alloy’s resilience to bending and fracture across an enormous range of conditions could open the door to a novel class of materials for next-generation engines that can operate at higher efficiencies.

Perfect crack-resistant metal alloy

The research was carried out by a team led by Robert Ritchie at Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley, in collaboration with the groups led by professors Diran …
