Microfractures in nano-size copper and platinum have been observed healing themselves from repeated tugs. The discovery could lead to the construction of self-healing structures and machines.
Of course, there are lots of industries whose product engineers would love to translate this finding into intentional engineering approaches to create metals that automatically heal themselves in our structural applications," lead-author Brad Boyce, a materials scientist at Sandia National Laboratories in Albuquerque, New Mexico, told Live Science. “Self-healing metals could be useful in a wide range of applications from airplane wings to automotive suspensions.”
