Abstract Mechanical properties and deformation mechanics at small scales of the bulk nanostructured Al–10Zn–2.8Mg–1.8Cu alloys before and after heat treatment were investigated by nanoindentation. The results showed that no clear change was found in the Yong's modulus (E) but the hardness (H) increased remarkably of the nanostructured alloys after T6 heat treatment. Obvious room temperature creep and notable shear bands were observed in the as–SPSed samples. In addition, room temperature creep became obvious and shear bands diminished with the increase of the strain rates. However, it was difficult to observe room temperature creep and shear bands in the as T6 treated samples. This phenomenon resulted from the changes of the distribution and morphology of second phase particles conducted by theT6 heat treatment.
