The low cycle fatigue behaviour of MAR-M247 superalloy under different strain rates and cycle shapes at 750?C
Original language description
High-temperature low-cycle fatigue experiments were performed at different strain rates on nickel-based su-peralloy MAR-M247. Furthermore, slow-fast, fast-slow and dwell-fatigue tests were conducted. The deformation, damage and lifetime behaviour as a function of strain rate and cycle shape were observed. Results show that the lifetime decreases with decreasing strain rate, indicating the negative influence of time-dependent creep and oxidation mechanisms. The lifetimes of slow-fast and dwell-fatigue tests are lower than those for fast-slow tests, although the mean stress is compressive in slow-fast and dwell-fatigue tests and tensile in fast-slow tests. Slowfast and dwell-fatigue tests lead to grain boundary cavitation.
