Heat Resistant Turbine Wheel Development of Automobile

Abstract:

Turbochargers of automobilehave been widely used in commercial vehicles by diesel engine. Nowadays, turbochargeris being tried to use passenger car by gasoline engine such as deluxe and compact car. Therefore, fabrication method and conditions of turbine wheel which is core parts ofautomobile turbochargers,arereviewed by Lost wax method. To fabrication of turbine wheel using Inconel 713C alloy, vacuum induction melting (VIM) with alumina (Al2O3) crucible was used. Inas- cast Inconel 713C alloy, the strength at the elevated temperature is not satisfied to commercial standard. Therefore, heat treatment was introduced in Inconel 713C alloy to increase strength. The strength at the elevated temperature was increased by aging treatment.
