According to new research, metals have the remarkable ability to heal themselves, just like the terrifying cyborg assassins in the “Terminator” movies. This discovery opens up possibilities for self-repairing engines, bridges, airplanes, and even rockets — which is especially promising for future manned missions to Mars.
In groundbreaking experiments, scientists were astonished to witness microscopic cracks disappear, offering hope for machines that can mend themselves on the spot.
“This was absolutely stunning to watch first-hand. 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,” says lead author Dr. Brad Boyce from Sandia National Laboratories in Albuquerque, in a media release.
Fatigue damage, resulting from repeated stress or motion, leads to the formation of tiny cracks in materials over time. These cracks grow and propagate until the entire device fails. This issue is of particular concern in spacecraft design, as a round trip to Mars takes at least 21 months.
