Abstract

A textured microstructure was produced in the TiAl turbocharger blades and platelike TiAl samples in the process of conventional casting, in which the lamellar orientation is parallel to the plate surfaces. A microstructure design specific to the turbocharger blades was therefore proposed based on the preponderance in tensile properties, creep rupture life and creep resistance along the preferential lamellar orientation. The mechanical capacity of the TiAl turbochargers has been validated through endurance tests. © (2009) Trans Tech Publications, Switzerland.
