- Abstract
The influence of temperature ramping ageing treatment on the microstructure and mechanical properties of Al-Zn-Mg alloy was investigated. When the final temperature was higher than 180°C, the hardness of the alloy improved with increase of the ramping rate. It increased and then decreased with increase of the ramping rate when the final temperature ranged from 180°C to 200°C. The tensile strength and electrical conductivity of the alloy after aging were improved as compared with the T6 state. As the ramping rate was increased and the final temperature was decreased, the distributed grain-boundary η-phase became continuous, and the size and spacing of η decreased, improving the resistance to stress corrosion of the alloy. These results indicate that temperature ramping ageing can improve the mechanical properties, corrosion resistance, and production efficiency of Al-4.11Zn-1.77Mg alloy with less time and energy consumption.
