In general, the platinum alloy is used in glass production lines, due to an excellent corrosion resistance to melted glass at high temperature. On the other hand, the development of high quality glass is needed, because of wide use of glass application in recent years. So, Oxide-Dispersion-Strengthened platinum alloy is developed which had better fatigue properties than the conventional one. However, there are few researches about the fatigue properties in a practical environment with axial stress and bending stress. Therefore, in order to clarify fatigue properties and fracture mechanism of Oxide-Dispersion-Strengthened platinum-10% rhodium with dispersed zirconium oxide particles, bending fatigue test at 1400°C, fracture surface observation and internal cross-section observation were performed. As a result of the fatigue test, it was clarified that the tendency of fatigue life with axial stress depends on the times to failure rather than number of cycles to failure. Also, it was clarified that the intergranular fracture and void generation due to creep occurred under the condition of axial stress of 23.4MPa.
