Magnetism, not melting: a lesson from 9/11

A news release from the BBC states that researchers are working towards a better understanding of the consequences of intense heat on metals from their research into the World Trade Center disaster.

It seems that heat, far below the melting point of metals in the WTC, altered the magnetism in the steel allowing the atoms to "slide past each other." A better understanding of this phenomenon may aid in the construction of facilities like nuclear reactors which need to withstand intense heat.
