Experts Design Elastic Iron for Surgeries, Buildings

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. 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 magnetisation. 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
