Embodiment Construction

[0034] In an advantageous embodiment, the aluminum-based alloy specified in the introduction comprises the element lanthanum. It has surprisingly been found that the element lanthanum in aluminum-based alloys has a positive effect on the stability of the material. Without being bound by theory, it is assumed here that the element lanthanum in Al-based alloys forms thermally stable Al3La phases (so-called age-hardening phases) that stabilize the microstructure in the alloy by forming microdendritic structures change. A particularly good creep strength is thus achieved in the material, with simultaneously increased heat resistance and vibration resistance.

[0035] It has also been found that the addition of lanthanum to aluminum-based alloys according to the invention has a considerable increase in strength both at room temperature (i.e. at about 20°C) and at component temperatures of about 220°C and even up to 300°C. Effect. It is also assumed here that this is due to this ...

Abstract

The invention relates to a compressor wheel for a turbocharger, in particular in combination with a diesel engine, and to an exhaust gas turbocharger comprising such a compressor wheel.

Description

technical field [0001] The invention relates to a compressor wheel for a turbocharger (in particular in combination with a diesel engine) according to the preamble of claim 1 and to a compressor wheel comprising a compressor wheel according to the preamble of claim 9 Gas turbocharger, and to a method according to the preamble of claim 17 for producing such a compressor wheel according to the invention. Background technique [0002] An exhaust turbocharger is a system designed to increase the power of a piston engine. In an exhaust turbocharger, the energy of these exhaust gases is used to increase power. The increase in power and reduction in emissions is a result of the increased throughput of mixture per working stroke. [0003] A turbocharger basically comprises an exhaust turbine with a shaft and a compressor, wherein a compressor wheel arranged in an engine intake is connected to the shaft and is located between the exhaust turbine and the compressor These vane wheel...
