| Abstract: | The impact and tensile properties of Al-3Li-0.17Zr alloy at different heat-treat -ment have been studied and correlated with the microstructure,deformation and frac- ture features observed by electron microscope.It is shown that the deformation and fracture mechanisms of different heat-treated alloys are different,and that there is an obvious difference between micro-features on the intergranular fracture stirface of those alloys. |
