AB In this study, the fretting fatigue behaviour of Inconel 718 was analysed at both room and high temperature (650◦C) using ‘dog-bone’ fretting fatigue specimens with a cylindrical contact pad. Inconel 718 is a nickelchromium-based superalloy widely used in the aeronautical industry due to its excellent mechanical properties, including resistance to oxidation and corrosion, even at high temperatures. Additionally, the material was heat-treated to enhance its mechanical performance. Different tests were conducted in the laboratory under various (axial) load levels to analyse the fretting fatigue behaviour of Inconel 718 at both temperatures. To achieve this, fretting fatigue and plain fatigue curves were obtained. In addition, interrupted fretting fatigue tests were carried out to gain a deeper understanding of crack evolution at elevated temperatures. The study was further complemented by an analysis of surface oxidation and the fracture surface of fretting fatigue specimens.
