Metal alloy shows practically no thermal expansion over extremely large temperature interval

Most metals expand when their temperature rises. The Eiffel Tower, for example, is about 10 to 15 centimeters taller in summer than in winter due to its thermal expansion. However, this effect is extremely undesirable for ...
