What specific material are the RR Trent XWB fan blades made out of?

For my Materials Science class, I have to pick a material (preferably a metal or alloy) and write about the process for making the material (from raw materials), describe the microstructure and properties of that are relevant to its application. I have looked at several sources online, and found that most Trent series engines' fan blades are made of a titanium alloy. But none of them state the name of the specific alloy that the blades is comprised of.

I'd really appreciate it if anyone could let me know what specific titanium alloy the Trent XWB fan blades are made of and if possible, any links/sources that could help me find more information.

Titanium alloy Ti-6Al-4V would be a good start. Try the search string, "6al 4v titanium fan blade" in Google.

The following appears to suggest that the Titanium alloy used for Trent fan-blades is indeed Ti-6Al-4V.

One way to possibly get more details on the alloy composition is to look up patents. RR have patented specific nickel alloys for turbo-machinery components.

Try the search string, "rolls royce titanium alloy patent". The below is a RR patented heat treatment method for titanium alumide

Anymore details than the above is likely to be proprietry information.

Nickel alloys are for hot turbine sections, not for fan.
Technology of single crystal nickel blades is nothing short of an eighth wonder of the world, though. If instructor doesn't know about it, that is a guaranteed jaw dropper .
