The compression behavior of a Ca 65 Mg 15 Zn 20 bulk‐metallic glass (BMG) was studied. The specimens showed no macroscopic plasticity. They fractured by exploding into many very small pieces. The Vickers hardness of the Ca 65 Mg 15 Zn 20 BMG was about 1.42 GPa. The fatigue limit for compression–compression fatigue was found to be about 140 MPa after 10 6 cycles. The fracture strength was inversely proportional to the fracture time. The proposed mechanism of the splitting and shear fracture modes clearly explained these properties.
