Effect of pre-rolling and aging temperature on the microstructure and mechanical properties of creep-aged 2050 Al–Li alloy

Autor: Guofu Xu, Mengjiao Liu, Shichao Liu, Lei Tang, Yao Li, Haoran Li, Jinfeng Li

Publikováno v: Journal of Materials Research and Technology, Vol 30, Iss , Pp 9037-9047 (2024)

The influences of aging temperatures (160–200 °C) and 8% pre-rolling on the mechanical properties, and microstructures of the creep-aged AA2050 alloys were investigated. The results show that for the solid-solutioned alloys after the creep aging,
