What type of materials are used to make up the different sections such as the linings of the combustion chambers in a gas turbine engine. Do these type of materials vary for the different types of gas turbine Engines such as the multiple-can type, annular and cannular.
This is more of an engineering question than an aviation question, but since some aviators may be interested in knowing exactly what is in those turbines I will answer.
There are three main types of refractory alloys commonly used for high-temperature components in turbine engines. They are:
Of the intermetallics that are used, there are two main types commonly used: NiAl (nickel aluminum) and TiAl (titanium aluminum).
