aluminium alloy for various strain amplitudes at temperatures of 20 ◦C, 160 ◦C and 195 ◦C. LCF tests at
elevated temperatures were performed for three different strain rates between 1 × 10−4/s and 1 × 10−2/s, while
fatigue–creep tests were performed with either tensile or compressive strain dwell. At 20 ◦C, cyclic hardening
was associated with a high dislocation density. In contrast, a localization of plastic deformation into slip
bands and cyclic softening were observed at 195 ◦C. The investigation of the damage mechanisms revealed
transgranular cracking as the predominant failure mode, significantly influenced by Al9FeNi intermetallic
particles. Finally, fatigue–creep tests were found to be more damaging than equivalent LCF tests, particularly
at 195 ◦C, where a negative strain rate sensitivity on fatigue lifetime was evident.
