Mechanical and Fatigue Behavior of Ca65Mg15Zn20 Bulk-Metallic Glass
The compression behavior of a Ca65Mg15Zn20 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 Ca65Mg15Zn20 BMG was about 1.42 GPa. The fatigue limit for compression–compression fa...

Summary: | The compression behavior of a Ca65Mg15Zn20 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 Ca65Mg15Zn20 BMG was about 1.42 GPa. The fatigue limit for compression–compression fatigue was found to be about 140 MPa after 106 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. |
