Bulk amorphous alloys have various kinds of superior properties such as high strength, excellent wear resistance and excellent corrosion resistance. In order to investigate the fatigue properties of Zr-base amorphous alloy in very high cycle regime, rotating bending fatigue tests were performed for 3 types of Zr_<55>Al_<10>Ni_5Cu_<30> sample. As results, S-N curve of Zr-base bulk amorphous alloy indicated clear fatigue limit and Zr-base bulk amorphous alloy has failed in the surface fracture mode even in very high cycle regime. Moreover, the statistical aspect on the fatigue property was analyzed as P-S-N characteristics by the method based on the JSMS standard.
