Experts design elastic iron for surgeries, buildings

Fri, Mar 19 2010

HONG KONG (Reuters) – Researchers in Japan have designed a super-elastic iron alloy which they hope can be used in sophisticated heart and brain surgeries and even buildings in earthquake zones.

In a paper published on Friday in the journal Science, 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.

The iron alloy’s stress level is about twice that of nickel titanium and it can be used to deliver stents, which are tubes placed in blood vessels to stop them from collapsing.
