Abstract The microstructure and deformation mechanisms of 8090 aluminum-lithium al-loy in superplastic deformation were investigated in this paper.TEM observations show that for8090 alloy under the optimum conditions of superplastic deformation(T=500℃,ε_i=3.33×10~

Key words: Al-Lialloy superplasticity multi-mechanism
