A series of open-cell bulk metallic glass foams (BMGFs) with different porosity content from 46% to 75% were successfully fabricated by a space holder technique. Morphologies of the foam, the amorphous nature and mechanical properties were systematically investigated by a combination of scanning electron microscope (SEM), X-ray diffraction (XRD), differential scanning carlorimetry (DSC), and compression test. The BMGFs possess Young's moduli ranging from 4 to 21 GPa and yield strength within 65-231 MPa, matching well with the moduli as well as yield strength of human bones and the predictions from theoretical models. These BMGFs are promising for bio-implant application without significant stress shielding effect.
