| Özet |
| In this study, the artificial ageing behavior (deformation ageing) of AA7075 Al-alloy is investigated. A certain part of the aluminum test pieces obtained commercially as T6 heat treated was solution heat treated at 480oC for 2 hours, then quenched in water. Test samples were strained for 8% in tension shortly after the solution heat treatment then aged at 140oC 0.5, 1, 2, 4 6, 8, 10, 12, 24, 36, 48, 72 and 96 hours in a furnace. In order to determine an effect of deformation ageing in the mechanical properties of aluminum alloys, the effect of ageing time on the ultimate tensile strength, yield strength,% elongation fracture and hardness were investigated in detail. The relationship between ageing and microstructure was also evaluated. During the deformation ageing, the ultimate tensile strength, yield strength, and hardness increased but, the% elongation fracture tendency decreasing at optimum ageing time. As a … |
