Fullerenes in crucible steel?

Fullerenes in crucible steel?

RE: Fullerenes in crucible steel?

On the Journalism scale of skepticism & believability, I would rate this about a "National Enquirer".  The cooling process from the molten state would have the carbon in solution in a liquid metal (non-ordered structure here).  Upon solidification (we'll skip the peritectic and delta iron, since I don't understand that part) and cooling to the austenite range, the carbon is dissolved in the steel, in an interstitial position within the face-centered cubic structure that is austenite.  You can't maintain a carbon bucky-ball structure here either.  Now cool the austenite slowly to form ferrite and carbide (Fe3C) which is, again, not a bucky-ball structure.

(OP)
Thanks.
I wasn't sure at what temp. the fullerene structures “disassembled“. I will be much more skeptical about fullerenes reported in steel structures anyway.  Gerald
