Özet
In this study, the effect of ageing temperatures in T6 heat treatment on the microstructural changing and mechanical properties of AA7075 were investigated. The samples were quenched after solution treatment at 485 degrees C for 2 h. The natural ageing was applied for 1 h, and then artificial ageing was carried out at five different temperatures (100-140 degrees C) for 24 h. Hardness measurements, microstructure, X-ray diffraction examinations, and tensile tests of aged samples were carried out. As a result of the study, the hardness values and ultimate tensile stress values were increased by increasing ageing temperatures up to 120 degrees C. Then it was decreased by increasing ageing temperature. Ultimate tensile stress values were compatible with hardness values and maximum ultimate tensile stress values were obtained in aged samples at 120 degrees C.
