Amorphous alloy ribbons have no crystalline structure and they have superiority in the electomagnetic and mechanical properties. Due to their useful electomagnetic property, the amorphous ribbons are widely used, nowadays, in the various products such as core of current transformers and electric motors. But we have a difficulty that the thickness of the amorphous ribbon is restricted within a certain value in order to realize the rapid quenching. Thus amorphous ribbons must be put together to some extent in order to use as mechanical components. In this study, a number of thin ribbons of Fe_<78>B_<13>Si_9 amorphous alloy are piled up and bonded by an adhesive. Statistical fatigue properties of such multilayer composites are examined by performing fatigue tests and fatigue mechanisms are discussed.
