... Abstract Abradable seals are a common technology employed to improve turbine engine performance by reducing the gap between blades and the casing in compressor and turbine stages. Because operating conditions and material requirements vary significantly as a function of turbine stage...

... and is lightweight, it is effective in reducing the moment of inertia of the turbine wheel. However, the TiAl material has a problem that it has high viscosity when it is melted and that it is not suitable for precision casting. Even when the thickness of the turbine wheel blades is increased to about 1 mm...
