Abstract

This paper presents the low cycle fatigue properties of extruded 6061 aluminum alloy. The cyclic strain-controlled fatigue tests were performed under fully reversed total with a strain amplitudes (0.51.3%) at a fixed strain rate (0.004 s1) using smooth specimens cyclically loaded along with the extrusion directions. The fatigue test results represented by the hysteresis curves of stress-strain show slight Bauschinger effect at a total strain amplitude (at)  0.7 %. At strain amplitudes  0.7% the alloy significantly experienced cyclic softening and in the strain amplitude ranging from 1.1 to 1.3 %, the alloy experienced cyclic hardening until the alloy failed. The corresponding cyclic stress response during fatigue loading revealed that cyclic softening occurred, particularly at the lower strain amplitudes and vice versa, at higher strain amplitudes the material experienced cyclic hardening. The strain-fatigue life models were empirically determined by the Coffin-Manson-Basquin relationships.
