Not all materials expand when heated. Some actually contract, including so-called thermal expansion material that include the iron-nickel composite Invar. Recent research in thermal expansion control has identified “one-component” metals that could be an alternative to Invar.
A team from NIST and the University of Maryland has found an iron-based superconductor that operates at the highest known temperature for a material in its class. The discovery inches iron-based superconductors—valued for their ease of manufacturability and other properties—closer to being useful in many practical applications.
