Abstract:	摘要： The (Ti 40 Zr 10 Cu 36 Pd 14 ) 100 − x Si x (x = 0, 0·5, 1·0, 1·5) bulk metallic glass (BMG) rods with a diameter of 2-4 mm have been successfully fabricated by suction casting method and characterised. The X-ray diffraction results reveal that these entire (Ti 40 Zr 10 Cu 36 Pd 14 ) 100 − x Si x alloy rods exhibit a typical amorphous diffraction pattern with only a broad maximum at 2θ∼40°. The optimum glass forming ability values γ and γ m (0·430 and 0·774 respectively) occur at the (Ti 40 Zr 10 Cu 36 Pd 14 ) 99·5 Si 0·5 amorphous alloy. This suggests that the Si element present a positive effect on increasing glass forming ability in the Ti 40 Zr 10 Cu 36 Pd 14 alloy system. The hardness of these Ti based BMGs exhibits an increasing trend with Si addition and saturated ∼710 HV. In addition, the result of compression test shows that the optimum mechanical property occurs at the (Ti 40 Zr 10 Cu 36 Pd 14 ) 99·5 Si 0·5 amorphous alloy, which presents 2050 MPa fracture strength and 8% failure strain. 出版者： Taylor & Francis 出版日期： 2015-08-14 出處： Materials technology (New York, N.Y.), 2015-08, Vol.30 (sup3), p.161-165 版權： 2015 W.
