Özet

In this study, the effect of cooling rate on microstructure and mechanical properties of Al-Mg-Si (6063) alloys was investigated. In order to obtain different cooling rate, samples heat treated at 520 degrees C for 2 h and then cooled in furnace, sand, air, oil and water environments. A decrease in the cooling rate caused the growth of grains and precipitates as the strength of Al-Mg-Si alloys reduced. As a result, Al-Mg-Si alloy was found to change significantly the properties of strength and forming depending on the cooling conditions.
