These airless Metl tires are made from nitinol, a shape-memory alloy that ‘stretches like rubber but is strong like titanium.’ Warning: Kickstarter. These airless Metl tires are made from nitinol, a ...

In the early 1960s, scientists discovered Nitinol, a nickel-titanium alloy with a shape memory effect. This remarkable material can be bent or deformed when cool but returns to its original shape when ...

(Phys.org) -- Shape-memory alloys (SMAs) are an engineer's dream, able to shape-shift spontaneously to accommodate changing operating conditions. A research team from the National Aeronautics and ...

A chance discovery in 1959 by military scientists led to Nitinol, a metal that remembers its shape. This nickel-titanium ...
