Hot tensile deformation behavior of 2195 Al–Li alloy was investigated at the temperature of 420–520 °C and the strain rates of 0.01–1 s−1. The mechanical characteristics and microstructural mechanism were discussed. Overall, the tensile strength increased with decreasing temperature and increasing s...
