%X Equal--channel angular pressed (ECAP) Al--Li--Cu--Mg--Zr alloy mainly consists of near equi--axial grains with size smaller than 1  m. ECAP Al--Li--Cu--Mg--Zr alloy cyclically softens continuously to failure at higher strain amplitude of   p/2=5.5 10 -3, but cyclically softens initially and then harden continuously to failure at lower strain amplitudes of   p/2=5 10 -4---2.6 10 -3. The Coffin--Manson curve of the ECAP Al--Li--Cu--Mg--Zr alloy shows an ideal straight line. All these properties are different from those reported previously for the conventional peak--aged Al--Li--Cu--Mg--Zr alloy.
