Patent ID: 7770291

Claim:
A process for producing an aluminum alloy component of an internal combustion engine, comprising: determining an area ( 2 ) of the component ( 1 ), which is highly thermally stressed during operation of the internal combustion engine, forming a melt in said highly thermally stressed area ( 2 ) of the component ( 1 ), introducing an additive ( 6 ) into the melt ( 5 ), wherein said additive is an aluminum alloy with a component of 1-2 wt. % silicon, less than 0.25 wt. % magnesium and less then 0.1 wt. % iron, and cooling said melt, such that said highly thermally stressed area ( 2 ) has a higher aluminum content than the overall component ( 1 ) and exhibits a higher breaking elongation than the overall component ( 1 ).
