| Abstract | Y, Gd, La and Ce were added into Zr(-Ti)-Cu-Ni-Al metallic glasses based on the mechanism of strong interaction between O and rare earth elements in order to control the O content and further to improve the glass forming ability and mechanical properties of the alloys. Metallic glasses were prepared by a copper mold casting method. The glass forming ability and microstructure of the alloys were studied by differential scanning calorimetry (DSC), X-ray Diffraction (XRD) and transmission electron microscopy (TEM), and the mechanical properties and corresponding fracture modes were investigated by quasi-static compressive tests and scanning electron microscope (SEM). The results show that the addition of Y improves the glass forming ability greatly. Bulk metallic glasses with the diameter over 10 mm can be prepared under relatively low vacuum. The compressive strength is up to 1950 MPa. |
