Abstract

This paper presents the low cycle fatigue properties of an extruded 6061 aluminum alloy. The cyclic strain-controlled fatigue tests were performed under fully reversed total strain amplitudes ranging from 0.5% to 1.3% at a fixed strain rate of 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 the total strain amplitudes (��at) � 0.7 %. The corresponding cyclic strain response revealed that the alloy underwent cyclic softening particularly at the lower strain amplitude (��at �0.7%) and at the higher strain amplitudes, the alloy tended to undergo cyclic hardening. The strain-fatigue life models were empirically determined by the Coffin-Manson-Basquin relationships.
