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.

添加Al对Ti35Zr15Ni40Cu10金属玻璃过冷液相区热稳定性和热塑性成形能力的影响

在本研究中，研究了添加 0.5 at% Al 对 Ti ₃₅ Zr ₁₅ Ni ₄₀ Cu ₁₀金属玻璃的热稳定性和热塑性成型能力的影响。非等温和等温 DSC 实验的结果表明，Al 的加入使过冷液体稳定。通过非等温（等温）DSC 实验获得的活化能为 Ti ₃₅ Zr ₁₅ Ni ₄₀ Cu ₁₀和 Ti ₃₅ Zr _14.5 Ni ₄₀ Cu ₁₀ Al _{0.5 的}活化能分别为 389 (540) 和 417 (558) KJ/mol， 分别。基于过冷液体较高的热稳定性，Al的加入提高了热塑性塑料的成型能力。Ti ₃₅ Zr ₁₅ Ni ₄₀ Cu ₁₀和Ti ₃₅ Zr _14.5 Ni ₄₀ Cu ₁₀ Al _0.5的最大填充深度_分别为~6.1 μm 和~7.5 μm。此外，计算了两种金属玻璃的F _mod参数以比较热塑性成型能力。所述˚F_国防部参数是6.65×10 ^-12 帕^-1和1.8×10 ^-11 帕^-1分别在Ti ₃₅ Zr ₁₅ Ni ₄₀ Cu ₁₀和Ti ₃₅ Zr _14.5 Ni ₄₀ Cu ₁₀ Al _{0.5 中}。
