Abstract 2195 Al-Li alloy thin-walled parts are widely used in the aerospace field. Improving the formability of 2195 Al-Li alloy is the basis and prere-quisite for achieving high-performance forming and manufacturing. In this work, uniaxial tensile tests with different temperatures (298—77 K) and different strain rates (0.000 25—0.01 s^-1) are used to study the effects of deformation temperature and strain rate on rheological law of 2195 Al-Li alloy at cryogenic temperature. The influence mechanism of deformation temperature on formability is analyzed by Erickson cupping experiment and the observation of fracture morphology. The results show that the elongation and tensile strength of the 2195 Al-Li alloy sample are increased by 78.11% and 71.13% respectively compared with room temperature when the deformation temperature is reduced from room temperature(298 K) to cryogenic temperature(77 K). And the Erichsen cupping index (IE) and maximum punch force increased by 19.2% and 51.4% compared with room temperature. At the same time, at cryogenic temperature, the work hardening rate of the material is higher than that at room temperature, and it has a larger stable plastic strain range, and the forming performance is significantly improved. Compared with room temperature, the size of the fracture dimples of the specimen decreases, the depth increases, and the distribution is more uniform. The fracture mode is a typical ductile fracture.
