| Abstract Scope |
In the present study, Ni60Nb20Zr20 and Ti50Cu28Ni15Sn7 metallic glass powders were synthesized separately by using a mechanical alloying technique. The dual-glassy-phased (Ti50Cu28Ni15Sn7)80(Ni60Nb20Zr20)20 powders were prepared by mixing the corresponding metallic glass powders. The dual- glassy-phased powders were then consolidated into bulk metallic glass/metallic glass (MG/MG) composite alloy discs. The amorphization status of as-prepared powders and bulk MG/MG composite discs was confirmed by X-ray diffraction and transmission electron microscopy. The microstructure of the MG/MG discs showed that the Ni60Nb20Zr20 phase is distributed homogeneously within the Ti50Cu28Ni15Sn7 matrix. The (Ti50Cu28Ni15Sn7)80(Ni60Nb20Zr20)20 MG/MG disc exhibited a relative density of 96.6% and its Vickers microhardness was 710 kg/mm2. |
