Enhancing mechanical properties and improving reliability of TiAl alloys by utilizing the mechanical anisotropy of the cast lamellar structure were reported. A self-oriented lamellar (SOL) microstructure was successfully produced in shaped components. After modification by hot isostatic pressing, such a microstructure exhibited improved mechanical properties. The TiAl rotor blades with SOL in a turbocharger passed rotation rig tests and showed enhanced engine performance.
