The unusual glass-forming ability(GFA) of the Zr_(48)Cu_(36)Ag_8Al_8 alloy and the high ductility of the Zr_(48)Cu_(36)Ag_8Al_8 metallic glass-matrix composites containing Ta powder were reported.The bulk metallic glass rod with a diameter of 25 mm was successfully synthesized using copper mold casting for the Zr_(48)Cu_(36)Ag_8Al_8 alloy.High GFA of this alloy was found to be related to a large supercooled liquid region and a quaternary eutectic point with low melting temperature.The bulk metallic glass matrix composites were prepared by introducing extra Ta particles into the Zr_(48)Cu_(36)Ag_8Al_8 melt.The composites consist of Ta particles homogenously distributed in the Zr_(48)Cu_(36)Ag_8Al_8 metallic glass matrix.The optimum content of Ta powder is 10at%for the composite with the highest plasticity,which shows a plastic strain of 31%.
