An optimum tensile elongation of 585% wasobtained at 540℃ and strain rate 1.67×10~(-2)s~(-1). The superplastic Al-Li alloy is ma-nufactured using thermomechanical processing: solution, overaging, warm rollingand recrystallization. Microstructural changes in thermomechanical processing andcavitation occurred during superplastic deformation have been observed. The super-plastic failure of alloy may be caused mainly by nucleation and growth of cavitiesas well as the linkage around grains.
