What about titanium?

Don't know. I think the answer here, is that it is too brittle to stand up
to the vibration, torque, and twisting.

Not that I know (because I don't know), but it doesn't make sense
that titanium would be an unsuitable material. Gas turbines using
titanium alloy compressors have been around for, well, decades. Sort
of an apples and oranges comparison, but still... On the other hand
google doesn't seem to turn up anything, and it _always_ seems to
turn up something (!?).
