Bei welcher Nioblegierung verspricht China einen Durchbruch?

This is a terrible title and the article doesn’t explain anything. The cool part is it can run like 70% hotter than SR-71 titanium which is literally the limiter for its operating speed. Would be a pretty significant advancement if true, if it doesn’t shed heat as well (likely?) or if we can’t or haven’t already figured out a better one.

Also this is much more likely missile tech than space tech, not that there’s much of a difference but this is only really useful in some amount of atmosphere.
