Compressor components are made from titanium-based alloys. I know Ti 6-4 is used quite a bit in blades, disks, etc.

What's a typical rotary EGT? I'm thinking all the titanium alloys I'm familiar with would not stand up to rotary combustion chamber temperatures and gases for very long. Titanium is poor in high-temperature oxidation and corrosion. Almost all modern-day turbine components (at least in the industry I work) are nickel-based. Inconels, Hastelloy, Waspalloy and other materials I can't name.
