PROCESS FOR MAKING ARTICLES OF ALUMINIUM ALLOY WITH IMPROVED FATIGUE STRENGTH

Aluminium alloy articles with an improved fatigue strength and process for their manufacture. These articles are made of an alloy containing, by weight, 11 to 22% of silicon, 2 to 5% of iron, 0.5 to 4% of copper, 0.2 to 1.5% of magnesium, having a characteristic of containing 0.4 to 1.5% of zirconiu...

Summary:Aluminium alloy articles with an improved fatigue strength and process for their manufacture. These articles are made of an alloy containing, by weight, 11 to 22% of silicon, 2 to 5% of iron, 0.5 to 4% of copper, 0.2 to 1.5% of magnesium, having a characteristic of containing 0.4 to 1.5% of zirconium. The manufacturing process consists in subjecting the alloy in molten state to a means for fast solidification, in forming it, in subjecting it to a heat treatment between 480 and 530 DEG C followed by a water quenching and by annealing between 150 and 200 DEG C. These articles find their application especially in the form of connecting rods and gudgeon pins.
