High-cycle fatigue (HCF) experiments were conducted on Zr41.2Ti13.8Cu12.5Ni10 Be22.5 bulk-metallic glass (BMG). The cast samples were machined into the notched fatigue specimens whose stress-concentration factor (Kt) is 1.55 of the stress acting over the notched section. The value of Kt was applied to the stress-range value and in good agreement with the numerical value obtained by our finite-element analysis (FEA). The fatigue results exhibit the fatigue-endurance limit of Zr41.2Ti13.8 Cu12.5Ni10Be22.5 to be about 30-40% of the ultimate tensile strength.
