Abstract

In the present study, the effect of the addition of 0.5 at% Al on the thermal stability and thermoplastic forming ability of Ti₃₅Zr₁₅Ni₄₀Cu₁₀ metallic glass have been investigated. The results of non-isothermal and isothermal DSC experiments show that the addition of Al stabilizes the supercooled liquid. The activation energies obtained by non-isothermal (isothermal) DSC experiments are 389 (540) and 417 (558) KJ/mol for Ti₃₅Zr₁₅Ni₄₀Cu₁₀ and Ti₃₅Zr_14.5Ni₄₀Cu₁₀Al_0.5, respectively. Based on the higher thermal stability of the supercooled liquid, the thermoplastic forming ability is improved with the addition of Al. The largest filling depths for Ti₃₅Zr₁₅Ni₄₀Cu₁₀ and Ti₃₅Zr_14.5Ni₄₀Cu₁₀Al_0.5 are ~ 6.1 μm and ~ 7.5 μm, respectively. Besides, the parameters of F_mod for the two metallic glasses has been calculated to compare the thermoplastic forming ability. The F_mod parameters are 6.65 × 10^–12 Pa⁻¹ and 1.8 × 10^–11 Pa⁻¹ in Ti₃₅Zr₁₅Ni₄₀Cu₁₀ and Ti₃₅Zr_14.5Ni₄₀Cu₁₀Al_0.5, respectively. Graphic Abstract: [Figure not available: see fulltext.]
