Turbine wheel of an exhaust gas turbocharger and associated production method

The invention relates to a turbine wheel of an exhaust gas turbocharger which may include a body composed of a TiAl alloy via at a metal injection moulding (MIM), selective laser melting (SIM) or electron beam melting (EBM). The body may have a quotient Q of a diameter dS defined by each of the outl...

Beschreibung
Zusammenfassung:	The invention relates to a turbine wheel of an exhaust gas turbocharger which may include a body composed of a TiAl alloy via at a metal injection moulding (MIM), selective laser melting (SIM) or electron beam melting (EBM). The body may have a quotient Q of a diameter dS defined by each of the outlet blade tips to a diameter dN defined by each of the outlet blade roots corresponding to the following relationship: Q=dS/dN>3.85 in this condition.
