Isothermal low-cycle fatigue and fatigue–creep behaviour of 2618 aluminium alloy

Original language description

A series of strain-controlled Low-Cycle Fatigue (LCF) and fatigue–creep tests were performed on a 2618naluminium alloy for various strain amplitudes at temperatures of 20 ◦C, 160 ◦C and 195 ◦C. LCF tests atnelevated temperatures were performed for three different strain rates between 1 × 10−4/s and 1 × 10−2/s, whilenfatigue–creep tests were performed with either tensile or compressive strain dwell. At 20 ◦C, cyclic hardeningnwas associated with a high dislocation density. In contrast, a localization of plastic deformation into slipnbands and cyclic softening were observed at 195 ◦C. The investigation of the damage mechanisms revealedntransgranular cracking as the predominant failure mode, significantly influenced by Al9FeNi intermetallicnparticles. Finally, fatigue–creep tests were found to be more damaging than equivalent LCF tests, particularlynat 195 ◦C, where a negative strain rate sensitivity on fatigue lifetime was evident.n
