英文摘要	Based on Cu-Zr-Al tenary alloy, the effects of addition of Ag and Fe elements on glass-forming ability and mechanical properties of Cu-Zr-Al-Ag and Cu-Zr-Al-Ag-Fe bulk amorphous systems were investigated. Cu50Zr42Al8 BMG exhibits high glass-forming ability and thermal stability in ternary alloy system, ΔTx, Trg and γ of which are 61 K, 0.624 and 0.416, respectively. The glass-forming ability of Cu-Zr-Al ternary alloy system is obviously improved with addition of Ag. In the quaternary system, Trg of Cu43Zr45Al8Ag4, Cu45Zr42Al8Ag5, Cu40Zr44Al10Ag6, Cu43Zr41Al8Ag8 and Cu36Zr48Al8Ag8 are 0.618, 0.625, 0.618, 0.628 and 0.598, γ of which are 0.424, 0.427, 0.424, 0.432 and 0.433, ΔTx of which are 77, 76, 78, 84 and 108 K, respectively. In the (Cu0.36Zr0.48Al0.08 Ag0.08)100-xFex(x = 0, 3, 5, 10, 15, 20) quinary system, the addition of Fe exists an obvious effect on the glass forming ability of the alloys. Although the ΔTx and Trg are reduced, the (Cu0.36Zr0.48Al0.08 Ag0.08)97Fe3 bulk amorphous alloy exhibits high glass-forming ability, and ΔTx, Trg and γ of this alloy are 103 K, 0.566 and 0.424, respectively. The compressive fracture strength and plastic strain of (Cu0.36Zr0.48- Al0.08Ag0.08)95Fe5 alloy increase to 2249 MPa and 4.9%, respectively, which shows that the addition of suitable Fe improves the mechanical properties obviously. The existence of Fe element results in the distinct phase separation in Cu36Zr48Al8Ag8 alloys, which strengthens and toughens the (Cu0.36Zr0.48Al0.08 Ag0.08)100-xFex alloy.
