ScienceDaily (June 9, 2011) — A Detroit entrepreneur surprised university engineers in Ohio recently, when he invented a heat-treatment that makes steel 7 percent stronger than any steel on record -- in less than 10 seconds.
If this pans out, an example of an application would be automobile frames, which could be 30% lighter, without sacrificing safety. Presumably, that would improve fuel economy.
If this seems a bit skeptical, one gets a bit jaded after hearing about advances that can do miracles, but never to be heard of again.
On the other hand, we do get improvements in technology that have accumulated over the years. If this can work, it would be a big help.
