This (almost) indestructible alloy is the hardest material on the planet

As if it were a superman of materials, we are dealing with a combination of elements resistant to almost any external aggression.

Present material present form nature In our planet, But given our status as curious creatures, we’ve spent centuries using our ingenuity to improve what nature has left for us on Earth. On other occasions, we’ve told you about the gold used in the James Webb Space Telescope and now we’re going to show you a newly discovered alloy and that has the honor of having really hard, Maybe not quite like Chuck Norris, but there’s nothing in the universe tougher than Chuck Norris. This ruthless durability test tortures the Samsung Z Fold 4: The results speak for themselves

There is no substance more difficult than this high-entropy alloy.

In it Berkeley National Laboratory And the University of CaliforniaTwo researchers have carried out a series of experiments on the so-called high entropy alloys, which are formed by combining large proportions of five or more elements, as we have seen in the study published on the Science website. in this case they are mixed chrome, cobalt and nickel Achieving a material that the researchers defined as having ‘exceptional tolerance to damage’.

one of its great discoveries new alloyCrCoNi, investigating how their strength properties improved upon cooling Which can be used in the future to build structures to survive cryogenic environments. iso george A metallurgy expert at the University of Tennessee assures Science Alert that:

When you design structural materials, you want them to be strong, but also ductile and resistant to fracture. Typically, it is a compromise between these properties. But this material does both and at low temperatures it becomes harder rather than more brittle.

loss researchers have used with CrCoNi temperature similar to that found in liquid nitrogen, which is usually located in -196ºCAnd this Result He has left them stone. it Alloy is at that temperature Capable of reaching 500 megapascals of hardness, To most mortals this data means nothing, but if we tell you that silicone hardness it is 1 megapascal that he aluminum used in airplanes 35 What? best steels are located around 100We are sure that you will understand the dimensions of the search.
