Abstract

Formation of NiTiZrAlCuSi amorphous alloy was investigated by using differential scanning calorimetry (DSC), differential thermal analysis (DTA) and X-ray diffraction (XRD). When prepared by using the simple copper mould casting, the maximum diameter of glassy rods increased from <0.5 mm for the Ni₄₂Ti₂₅Zr₂₅Al₈ alloy to 1 mm for the Ni₄₂Ti₂₀Zr₂₅ Al₈Cu₅ alloy and to 4 mm for the Ni₄₂Ti₂₀Zr_21.2 Al₈Cu₅Si_3.5 alloy. The maximum reduced glass transition temperature T_rg(= T_g/T₁) of 0.570 and the maximum supercooled liquid region △ H(= T_x-T_g) of 93 K were attained in Ni₄₂Ti₂₀Zr_21.5 Al₈Cu₅Si_3.5 and Ni₄₂Ti₂₀Zr_20.5 Al₈Cu₅Si_4.5 alloys, respectively. Addition of a proper amount of Si can effectively enhance the glass-forming ability by suppressing the formation of primary Ni(TiZr) and (TiZr) (CuAl)₂ phases. The compression test at room temperature showed that the Ti₄₂Ti₂₀Zr_21.5 Al₈Cu₅Si_3.5 alloy has a high fracture strength of 2724 MPa.
