| 摘要 | Fatigue life, surface deformation morphology, fatigue cracking and fatigue fractography of Al-0.7%Cu (mass fraction) alloy, produced by equal channel angular pressing (ECAP) for 4 passes, were investigated under constant stress or plastic strain control. It is shown that the specimens displayed obvious cyclic softening, which caused some difference in fatigue life at low or high stress range under constant stress and strain conditions. The plastic strain is carried either by shear bands only, or by shear bands and deformation bands, in the specimens fatigued under strain control. Consequently, fatigue cracks nucleated either along shear bands or along deformation bands. However, the plastic strain only localized in the shear bands of the specimens under stress control, as a result, leading to shearing fatigue cracking. The fatigue fractography consists of several different zones, including fatigue crack initiation, slow, fast propagation and final fracture. |
