Abstract
The low cycle fatigue behaviour of Udimet 500 was investigated at an elevated temperature, i.e. 700°C (973 K). The influence of the cycle period was studied in the range 2–2000 s using a triangular waveform signal, except for one test. Microstructural observations by means of optical, scanning and transmission electron microscopy were extensively employed in order to determine the cycle period for which the material exhibits softening in terms of maximum stress. These qualitative observations indicate that, for this material, two ranges of cycle period exist: from 2 to 500 s during which the Udimet 500 alloy strengthened and from 500 to 2000 s during which the material progressively softened. Quantitative measurement of the volume fraction of deformation bands in the specimen indicates that the maximum volume fraction corresponds to the test conducted at 500 s. A deformation mode study shows two types of dislocation configuration: the first, for periods from 2 to 500 s, reveals cells and deformation bands; the second from 500 to 2000 s exhibits numerous stacking faults. Analysis of the nature of these stacking faults and identification of the Burgers vector of Shockley partial dislocations was also conducted. On the basis of these two types of deformation mode an explanation of the cyclic behaviour of the alloy is proposed.
