【 摘 要 】

This study was conducted with the aim to investigate the high temperature oxidation behavior of Inconel 750 alloy, which has excellent high temperature corrosion resistance among Ni-based super alloys. In the study, the temperature was set at 700°C, 900°C and 1100°C in the atmospheric environment; the heat treatment holding time was increased to 1 hour, 6 hours and 12 hours at each temperature to investigate the weigh increase behavior at each condition; and the shape of the oxide layer formed on the surface and the distribution of the elements were analyzed by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS).
