Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A compressor wheel for a turbocharger, comprising an aluminum-based alloy having a dendritic phase microstructure, wherein the aluminum-based alloy comprises the following components: Fe: 0 to 5.0% by weight, Mn: 0.16 to 2.8% by weight, Cu: 2.7 to 5.0% by weight, Si: 0.3 to 2.05% by weight, Mg: 0.2 to 1.9% by weight, Ti: 0.05 to 1.3% by weight, Zr: 0.1 to 0.3% by weight, La: 0.1 to 0.5% by weight, Ni: 0.45 to 2.6% by weight, Ce: 0.1 to 0.5% by weight, B: 0.01 to 1.35% by weight, in each case based on the total weight of the alloy and Al as balance. 2. An exhaust gas turbocharger for diesel engines, comprising a compressor wheel consisting of an aluminum-based alloy having a dendritic phase microstructure, wherein the aluminum-based alloy comprises the following components: Fe: 0 to 5.0% by weight, Mn: 0.16 to 2.8% by weight, Cu: 2.7 to 5.0% by weight, Si: 0.3 to 2.05% by weight, Mg: 0.2 to 1.9% by weight, Ti: 0.05 to 1.3% by weight, Zr: 0.1 to 0.3% by weight, La: 0.1 to 0.5% by weight, Ni: 0.45 to 2.6% by weight, Ce: 0.1 to 0.5% by weight, B: 0.01 to 1.35% by weight, in each case based on the total weight of the alloy and Al as balance. 3. A compressor wheel for a diesel engine turbocharger, comprising an aluminum-based alloy having a dendritic phase microstructure, wherein the aluminum-based alloy comprises the following components: Fe: 0 to 5.0% by weight, Mn: 0.16 to 2.8% by weight, Cu: 2.7 to 5.0% by weight, Si: 0.3 to 2.05% by weight, Mg: 0.2 to 1.9% by weight, Ti: 0.05 to 1.3% by weight, Zr: 0.1 to 0.3% by weight, La: 0.1 to 0.5% by weight, Ni: 0.45 to 2.6% by weight, Ce: 0.1 to 0.5% by weight, B: 0.01 to 1.35% by weight, in each case based on the total weight of the alloy and Al as balance.
