Default Stronger Steel

Since I happened to be posting stuff on Pulse Detonation Engines,
which heavily tax their materials due to the terrible cylical
mechanical and thermal stresses which can cause fractures, I thought I
would post this little article mentioning a new advance in
higher-strength steel:

http://www.physicsweb.org/article/news/7/7/14

So basically, it says that smaller nano-particles are able to
strengthen the steel in its weak spots, but it's not quite clear on
whether the new steel has only a slight amount of carbon in it, or
whether it has just slightly more carbon in it than regular steel.

I wonder whether PDEs would be made of steel to begin with, but in any
case, a much stronger steel could make itself a strong candidate.
