Metal heals itself?

[FredC]

Short article about metal healing nano cracks. Seems to be a newly observed phenonium.

A Cracked Piece of Metal Healed Itself in an Experiment That Stunned Scientists

File this under 'That's not supposed to happen!': Scientists observed a metal healing itself, something never seen before.

This science alert place is interesting. A short article about puss caterpillars.
The article describes the pain inflicted by their venom. As one that has been stung by these little beasts twice I rate the pain a second only to a bad migraine. My experience was intense burning pain plus temporary paralysis.

This Fuzzy Caterpillar Conceals a Venom Unlike Any Ever Seen in Insects

Caterpillars with a notoriously painful sting may have evolved their venom with help from ancient microbes, according to a new study led by scientists from the University of Queensland in Australia.

Watch out for those little beasts, just barely brushing against them will be a mistake you will remember for years.

The cold welding phenomenon has been about a while, we had a slip gage stack in work under a sine table, when the stack was taken out it had become a single entity, one solid bar, belting with a hammer stuck.
Fascinating.

Self healing metal has been around for years, if you watch Terminator 2 you can see that android guy is made out of liquid metal that re-forms with no problem.

Saw that on the wire this morning as well.

Might work in the (excellent) vacuum of an SEM, but would the same thing happen in air? Cold welding is a long standing concern in spacecraft.

Zinc plating is self healing as well Look at cut sheetmetal that is plated Those edged do not rust that easy eighter Look carefull and you see zinc on the cut edge

I know a guy with a rollercoaster who could use some of that

Something similar but more practical has been observed in the real world for decades. Both cam lobes and gear teeth, if they get micropitting from bad lube or other causes, if you drop the load back and make sure the oil is good, the metal will self-heal in operation after a time. Not exactly the same thing, but more useful.

Is this like the golf balls infused with lizard DNA so that the cuts self heal and duck DNA so you don't lose them in the water hazard.
