Using advanced computer simulations, the researchers analyzed the invar effect in detail and developed a pyrochlore magnet—an alloy with improved thermal expansion properties compared to invar. Metal ...

A research collaboration has created a pyrochlore magnet alloy with near-zero thermal expansion, outperforming Invar. This breakthrough, based on advanced computer simulations, stabilizes materials ...

Invar, for example, an alloy of iron and nickel, is known for its extremely low thermal expansion. How this property can be explained physically, however, was not entirely clear until now.

An alloy of iron and nickel called Invar is one known material with an extremely low thermal expansion that is used to create precision instruments such as clocks and some engine valves.

Things are known to expand when they get hot. Bridges, roads, and even the Eiffel Tower grow a little taller in the summer. The Eiffel Tower’s height changes by 10 to 15 centimeters between ...

The two studied a metal alloy of iron and nickel called Invar, which is known for its low coefficient of thermal expansion. Invar was discovered in 1896 by Swiss physicist Charles Édouard ...
