Stunned Researchers Discover that Metals Can Heal Themselves 'Without Human Intervention'
Scientists for the first time have witnessed pieces of metal crack, then fuse back together without any human intervention, overturning fundamental scientific theories in the process.
If the newly discovered phenomenon can be harnessed, it could usher in an engineering revolution—one in which self-healing engines, bridges, and airplanes could reverse damage caused by wear and tear, making them safer and longer-lasting.
The research team from Sandia National Laboratories and Texas A&M University described their findings today in the journal Nature.
“This was absolutely stunning to watch first-hand,” said Sandia materials scientist Brad Boyce.
“What we have confirmed is that metals have their own intrinsic, natural ability to heal themselves, at least in the case of fatigue damage at the nanoscale,” he told the Laboratory’s press.
