Abstract

Size effects on bending fatigue characteristics are investigated on Zr-based bulk-metallic glasses (BMGs). The fatigue lifetimes and endurance limits of the large-size samples are greater than those of the small-size samples. The results suggest that although a BMG exhibits good ductility due to the formation of multiple shear bands when its size decreases, the fatigue resistance of BMGs might degrade when the specimen size becomes smaller. The current study finds that small-size BMG samples under bending fatigue could fail in the flexural or fracture mode.
