Effect of two-stage aging on superplasticity of Al-Li alloy LUO Zhi-hui(罗智辉), ZHANG Xin-ming(张新明), DU Yu-xuan(杜予晅), YE Ling-ying(叶凌英) School of Materials Science and Engineering, Central South University, Changsha 410083, China Received 28 July 2006; accepted 15 September 2006 Abstract: The effect of two-stage aging on the microstructures and superplasticity of 01420 Al-Li alloy......
developed by using Gleeble test data show three domains in the tested range. Superplasticity, marked by abnormal elongation at 700 ℃, occurs in the temperature range of 650-750 ℃ and at strain rates below about 0.03 s-1. Large grain superplasticity takes place in the temperature range of 750-850 ℃ and strain rates range of 0.001-0.03 s-1. Dynamic recrystallization occurs in the temperature range......
