A Cracked Piece of Metal Self-Healed in Experiment That . . . File this under 'That's not supposed to happen!' In an experiment published in 2023, scientists observed a damaged section of metal healing itself Though the repair was only on a nanoscale level, understanding the physics behind the process could inspire a whole new era of engineering
“Absolutely Stunning” – Scientists Discover Metals That Can . . . For the first time, scientists have observed metal spontaneously healing its microscopic cracks, a phenomenon that contradicts conventional material theories and opens a new frontier in engineering and materials science (Artist’s concept ) Microscopic cracks vanish in experiments, revealing possibility of self-healing machines
Scientists Just Watched Metal Heal Itself—and They Can’t . . . A cracked piece of metal fused itself back together in a lab—and no one was prepared for it In a 2023 experiment, researchers at Sandia National Laboratories and Texas A M University were stress-testing a strand of platinum under a microscope
Scientists Stunned by Self-Healing Ability of Cracked Metal . . . With a loss of hundreds of billions of dollars Though scientists had developed mainly plastics as self-healing materials, a self-healing metal was considered unreal, according to SciTechDaily Cracks were expected to grow bigger, not smaller, and even basic equations did not account for the possibility of such healing processes in metals
Scientists stunned after cracked piece of metal self-healed . . . Boyce reiterates that cracks in metals only tend to get bigger, with basic equations suggesting such a healing process would be unlikely The study says that the first known incident of metal 'healing' itself without human intervention could overturn 'fundamental scientific theories in the process'
Stunning discovery: Metals can heal themselves - ScienceDaily Although scientists have created some self-healing materials, mostly plastics, the notion of a self-healing metal has largely been the domain of science fiction "Cracks in metals were only ever
