| 中文摘要 | A Ti(33)Cu(47)Zr(9)Ni(6)Sn(2)Si(1)Nb(2) bulk metallic glass has been developed by Nb partial substitution for Zr in Ti(33)Cu(47)Zr(11)Ni(6)Sn(2)Si(1) alloy. The glass forming ability Ti(33)Cu(47)Zr(9)Ni(6)Sn(2)Si(1) Nb(2) alloy has been investigated using differential scanning calorimetry and X-ray diffractometry. Partial Nb substitutes for Zr promote the glass forming ability. Ti(33)Cu(47)Zr(9)Ni(6)Sn(2)Si(1) Nb(2) BMG with diameter of 3 mm can be fabricated by Cu-mold injection casting method. The glass forming ability of Ti(33)Cu(47)Zr(9)Ni(6)Sn(2)Si(1) Nb(2) alloy is enhanced by stabilizing the undercooled liquid against crystallization. The plastic strain up to 2.5% was obtained for Ti(33)Cu(47)Zr(9)Ni(6)Sn(2)Si(1) Nb(2) BMG compared to 0.15% for Ti(33)Cu(47)Zr(11)Ni(6)Sn(2)Si(1) BMG, which demonstrates that small amount of Nb addition can have a dramatic effect on plasticity enhancement in Ti-Cu-based BMG. The intersection and branching of the shear bands are observed. The plastic strain of the Ti(33)Cu(47)Zr(9)Ni(6)Sn(2)Si(1) Nb(2) BMG can be improved by the generation of nanocrystalline particles, which lead to multiple shear bands. (C) 2010 Elsevier B.V.
