  Concorde Low Pressure Turbine Nozzle Guide Vane.
From the source: "Low Pressure Turbine Nozzle Guide Vane (NGV), seldom seen and much harder to find than rotor and stator blades from the compressor stages. This blade\[CloseCurlyQuote]s part number is B515719. The NGV blade sits behind the combustion chamber and high pressure turbine assemblies, between the high pressure turbine rotor and low pressure turbine rotor. It is for this rotor assembly the NGV smooths and slows the airflow for. There are 24 of these in the assembly within the engine."
This vane is made of waspaloy, a nickel-based superalloy with the following approximate composition:
Ni 60%
Cr 20%
Co 13%
Ti 3%
Mo 4%
Plus smaller amounts of C, B, Al, an Zr.
