heated the strip to more than 100 °C. As if commanded by an
enigmatic force, it straightened out like a tight spring and lifted
the load. When the current was switched
off, the strip gradually
went back to its original shape. The cycle was repeated a number
of times, and the strip always "remembered" its original shape.
The surprising phenomenon of direct conversion of thermal
energy into mechanical is seen with the naked eye.
7. The explanation is in the crystalline modifications of
titanium-nickel alloy which, changing with the temperature, also
changes back again.
