Abstract
The invention relates to aluminium alloy parts having an improved fatigue strength and to their production process. These parts are made from an alloy containing by weight 11 to 22% silicon, 2 to 5% iron, 0.5 to 4% copper, 0.2 to 1.5% magnesium and having the characteristic of containing 0.4 to 1.5% zirconium. The process for obtaining the same consists of subjecting the alloy in the molten state to fast solidification, shaping, a heat treatment at between 480.degree. and 530.degree. C., hardening with water and tempering at between 150.degree. and 200.degree. C. These parts are more particularly used as rods and piston pins.
