Abstract
In order to study the tensile properties of Al–Li alloy 5A90 at high temperature, the Al–Li alloy sheet metal with a thickness of 1.6 mm was obtained by rolling the original plate with the original thickness of 7.3 mm. Universal tensile tests of the previously rolled sheet metals were carried out in the temperature range of 375–450 ℃ with a strain rate of 0.002 s−1. The experimental results show that the elongation of the material reaches 600% at the temperature of 425 ℃, the true strain reaches 2.0, and the peak stress at this temperature is 8.0 MPa.
