Shape memory alloys (SMA) remember their original shape and return to it after being heated. Similar to how a liquid transforms into a gas when boiled, SMAs undergo a phase transformation when heated ...

The advancement in materials science and manufacturing systems has shown various industrial revolutions. Introduction of shape memory alloys (SMAs) is of that revolution due to its development due to ...

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 ...

(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 ...

We use the words “intelligent” and “smart” to describe functional materials with unique features, such as the ability to take on preferred shapes at different temperatures 1. Shape memory alloys (SMAs ...

NASA engineers are developing a new type of wheel using a shape-memory alloy made from nickel and titanium. Unlike traditional rubber tires, these metal wheels do not rely on air pressure and can ...
