Not before Ayn Rand they didn't.

    This is fascinating! I'm curious to find out what the solution will be regarding the coating that prevents oxidation. I wonder that an oil hasn't been used?

    That's a very interesting read. Many moons ago I was doing metallurgy research at Boeing. At that time I was working with aluminum alloys that were in the strength range of steel. If you have flown on a 777 you were lifted by one particular alloy I helped select in the structure. Fantastic metals for aircraft! Now, they're going to more composites (plastic crap).

    It sounds like the work these guys are doing is resulting in a metal a little more complicated to process/handle than your common "skyscraper" steel. Note the cold working mentioned in the article, and the special tempering. Good read...brings back memories.

    Big boost to transportation industry and fuel savings. I think electric cars will be beneficiary, and might compete with the light weight diesel engine for my sports car (that doubles as a private plane.) Elon Musk might be a good partner.

    Before that we'll read about how it's a threat to existing steel mills and the National Society of Profession Engineers has said any damages resulting from the use of the new material will cause the engineer who stamped the plans to be personally liable regardless of the fact pattern of the failure.

    This is a very clever variation on precipitation hardening. I should have thought of this!
