Abstract: Tensile fracture of an Al-Li-Cu-Mg-Zr alloy 8090 was studied. The results showed that the tensile fracture of the alloy contains dimples and intergranular rupture as well as cleavage facets, and the cleavage facets are formed by the interaction of inclusions and Na element.

Key words: Al-Li alloy tensile fracture dimple rupture cleavage
