EN AW 6082 alloys are used in many different areas from construction to structural applications and from automotive to aerospace industry. Having the highest strength and corrosion resistance in the 6XXX group, EN AW 6082 also has greater weldability, formability and machinability. Since studies on this industrially important alloy the homogenization and cooling are limited. The cooling rate is one of the main factors determining the distribution and density of the precipitates in the grain. Billet samples homogenized for 3 hours at 550˚C and cooled at 50˚C h-1,100˚C h-1 250˚C h-1 500˚C h-1 and 1000˚C h-1 cooling rates, respectively. It is aimed to characterize the precipitates formed with different cooling rates and to observe their behavior. The microstructure difference between the cooling rates were determined. The amount of precipitate increases with decreasing cooling rate. On the contrary, a significant reduction of precipitation was observed at 1000˚C h-1 cooling rate.
