In a groundbreaking discovery, scientists have for the first time observed metal spontaneously healing its microscopic cracks, upending traditional material theories. This observation could lead to self-healing machines, significantly enhancing their safety and lifespan. The phenomenon, confirming a theory proposed in 2013, may pave the way for an engineering revolution, though further research is necessary to fully understand its practical applicability.
For the first time, scientists have observed pieces of metal spontaneously cracking and then fusing back together. This groundbreaking observation contradicts long-held scientific theories and may pave the way for an engineering revolution. If the newly discovered phenomenon can be harnessed, the potential applications are wide-ranging and include self-healing engines, bridges, and airplanes that could autonomously repair damage caused by wear and tear, thereby enhancing their safety and longevity.
The discovery was made by a research team from Sandia National Laboratories and Texas A&M University. Their findings were described on July 19 in the journal Nature.
