That's a pretty cool article (didn't see the original site, thank goodness). I only read the teaser portion as I'm too tight to pay for a subscription. That sounds similar to a cryogenic treatment that a company was using on engine blocks recently (would that be considered reverse-heat-treating?). Can't remember much about it except that it made the bores last a lot longer and increased strength maybe. This sounds a little different than that. Technology is an amazing thing.
