Good:
Promising field
Compositions (incredibly weird alloying possible) which can boost useful performance to 300C.
Oxide-dispersion-strengthened alloys - mechanical alloying is a (the) route to these.
Unfortunately, typically have a "wrought" route but with very expensive material and large metal losses in machining are economically highly unfavorable.
Bets on "intelligent" open-die forging with many "tools" to form components given a 3-D solid model?
