    Abstract: Components include a low pressure turbine (20) having a plurality of rotor assemblies (100A, 100B) including a first gamma TiAl intermetallic blade (54A) having a maximum operating temperature over 1180°F (638°C). At least two of the rotor assemblies include gamma TiAl intermetallic alloy blades. In an embodiment, a method of making a turbine (20) having a plurality of rotor assemblies (100A, 100B) includes attaching a first gamma TiAl intermetallic alloy blade (54A) to an upstream stage of the plurality of rotor assemblies.
