Japanese Researchers Announce Development of Super-Elastic Iron Alloy

Japanese researchers published a paper in the journal Science, which has the promise of extreme value throughout the entire world. At present, nickel-titanium is the most widely used material for its strength and flexibility. But these researchers report that their new alloy can withstand twice the stress of that or nickel-titanium. It also has super-elasticity according to their report.

Nickel-titanium is used extensively in the medical profession and is used to build the tiny tubes through which stents are positioned in clogged blood vessels to the heart, neck, legs etc. The present usage, however is restricted to the larger sized veins and the materials have not enough strength to make them small enough to enter tiny vessels such as those in the brain.

The report in Science however, indicates that the newly developed alloy can be used in much smaller tubes and resulting veins, even into the brain, because of its strength coupled with it's elasticity.

The researchers said the metal's super-elasticity allows it to return to its original form and gives it additional properties, such as ductility and a change in magnetization (Taipei Times online: Super-elastic iron Introduced)

But aside from this medical advancement, the alloy reportedly will be outstanding in the construction of buildings, especially those in earthquake zones. They state that this material can be stretched greatly and still return to it's original position. The discovery gives forth great anticipation if only it performs as is expected.

Great information Joel. Let's hope it goes toward medicine and construction, and not guns.

Hi E. Ray, thanks for reading and commenting. I expect, if the fact are proven to be as they think, that it will primarily be for those two uses.

Yes, maybe so, plus the earthquake constrution advantage. Sounds good if it pans out to be as they say. Thanks for reading and commenting, Marijo.
