Abstract

PURPOSE: To obtain a turbine wheel that is lightweight, has a good response and is easy to manufacture, by forming the wheel and a shaft integrally, and at the same time, using for these materials TiAl and/or Ti3Al.
CONSTITUTION: A turbo charger at an internal combustion engine rotates a turbine wheel by means of exhaust energy, and at the same time, pre-pressures intaken air or the like by driving a compressor by this rotary force. In this instance, the turbine wheel 1 is so formed that a wheel main body and a shaft 2 are formed integrally, and at the same time, TiAl and/or Ti3Al are used for these materials. And when manufactured, a vacuum casting is conducted by using, for example, a ceramic shell casting mold. Also, a border portion 7 between the turbine wheel 1 and the shaft 2 is formed, for example, into an R surface shape (R>1). As a result, the turbine wheel 1 that is lightweight, and has a good response, and also, is easy to manufacture, is obtained.
