  • Mg60Cu30-xY10Six(x=0,1.0,1.8,2.5,5.0) bulk amorphous alloys were prepared by copper mould casting. The experimental results show that the alloy with x=1.0 has the largest glass-forming ability among Mg60Cu30-xY10Six(x=0, 1.0, 1.8, 2.5, 5.0) alloys. The microhardness and fracture toughness of Mg60Cu29Y10Si1 alloy are also significantly improved compared with those of Mg60Cu30Y10 alloy, but its supercooled liquid region (ΔTx) decreases slightly. However, the reduced glass transition temperature (Trg) of Mg60Cu29Y10Si1 alloy is larger than that of Mg60Cu29Y10Si1 alloy.
