20.500.12556/RUL-148321 Microstructure, mechanical properties and fatigue behaviour of a new high-strength aluminium alloy AA 6086 This study presents the comprehensive experimental investigation of the microstructure, mechanical and fatigue properties of a new high-strength aluminium alloy AA 6086, which was developed from a commercial aluminium alloy AA 6082. The new alloy possesses a higher content of Si, and, it also contains Cu and Zr. The alloy was characterised in the as-cast condition after homogenisation, extrusion, and T6 heat treatment. Light microscopy, scanning and transmission electron microscopy with energy dispersive spectrometry were used to analyse the microstructure and the fractography of broken specimens. The quasi-static and fatigue tests were performed on the MTS Landmark 100 kN servo-hydraulic test machine, controlled with a mechanical extensometer with a 25 mm gauge length. The quasi-static strength of the analysed aluminium alloy AA 6086 was found to be significantly higher if compared to some other AA 6xxx alloys, while the ductility was kept almost the same. The experimental results of the comprehensive fatigue tests in a Low Cycle Fatigue (LCF) and High Cycle Fatigue (HCF) regime showed a good fatigue resistance, and represent a good basis for engineering design applications of the newly developed aluminium alloy AA 6086. aluminium alloy AA 6086 material characterisation fatigue behaviour experimental testing statistical evaluation aluminijeve zlitine karakterizacija materiala utrujanje eksperimentalno testiranje statistično ovrednotenje true false true Angleški jezik Slovenski jezik Članek v reviji 2023-08-11 14:32:46 2023-08-11 14:32:47 2025-08-08 13:22:32 0000-00-00 00:00:00 2023 0 0 13 str.
