摘要

In the present study, amorphous Mg49Y15Cu 36, and Ti50Cu28Ni15Sn7 alloy powders were synthesized separately by using a mechanical alloying technique. The dual-phase (Mg49Y15Cu36) 100-x(Ti50Cu28Ni15Sn7)x (x = 0, 10, 20, 30, 40, and 50 vol%) powders were prepared by mixing the corresponding amorphous powders. The amorphous dual-phase powders were then consolidated into bulk metallic glass (BMG) discs. The amorphization status of as-prepared powders and BMG discs was confirmed by X-ray diffraction and by using a differential scanning calorimeter. The microstructure of the BMG discs showed that the Ti50Cu28Ni15Sn7 phase is distributed homogeneously within the Mg49Y 15Cu36 matrix. The (Mg49Y15Cu 36)50 BMG disc exhibited a relative density of 97.2% and its Vickers microhardness was 526 ± 20kg/mm2.
