well seeing how titanium is used as compressor blades in turbine engines.
The SR71 Blackbird is 95%+ titanium seeing any where from 500 to 3000+ degrees F at mach 3+
It's used as intake and exhaust valves in all forms of race engines, head studs for Top fuel engines at 8000 hp.
I question brittle. Figuring out the expansion rate for proper clearances at operating temps mint be a little tough.
Machining it's a bitch and aircraft quality billet is pricey.
