Abstract
In this study, the effect of pre-aging time and temperature on mechanical properties of aluminium alloys 6082 and 7075 has been investigated. Pre-aging has been applied at 50, 60, 70 and 80 degrees C for 24, 72, 144 hours after solution treatment process at 560 degrees C for 1 hour. Then these samples have been subjected to an aging process at 180 degrees C and 125 degrees C. The hardness of samples has been measured during aging process regularly. Eventually, it was determined that if pre-aging process is performed at low temperature, an increase of hardness occurs and hardness decreases with increasing temperature during aging.
