Abstract

Rotating bending fatigue tests were performed for Inconel 718 at room temperature and elevated temperatures of 300°C, 500°C and 600°C to investigate the influence of temperature on the fatigue crack initiation and its propagation. Although the propagation of a micro-crack smaller than about 20 um is suppressed at elevated temperatures, that of the larger-crack is accelerated inversely. These results were discussed from the viewpoints of the softening of matrix and the oxidation of surface caused by the high temperature.
