研究了 Fe 替代 Ni 对 Ni-B-Si-Nb 玻璃合金的玻璃形成能力 (GFA) 和机械性能的影响。 Fe 替代 Ni 导致 GFA 和机械性能增加。在 [(Ni1−xFex)0.75B0.2Si0.05]96Nb4 合金系统中形成直径达 3mm 的镍基大块玻璃合金 (BGA)。 BGA表现出3680-3840MPa的超高断裂强度和172-186GPa的杨氏模量，这是镍基BGA的最高值。 GFA 和断裂强度的改善被解释为通过添加 Fe 增强了组成元素之间的原子键合性质。
The effects of replacement of Ni by Fe on the glass-forming ability (GFA) and mechanical properties of Ni–B–Si–Nb glassy alloys were examined. The substitution of Fe for Ni caused increases of GFA and mechanical properties. Ni-based bulk glassy alloys (BGAs) with diameters up to 3mm were formed in a [(Ni1−xFex)0.75B0.2Si0.05]96Nb4 alloy system. The BGAs exhibit a superhigh fracture strength of 3680–3840MPa and Young’s modulus of 172–186GPa, which are the highest values for Ni-based BGAs. The improvement of GFA and fracture strength is interpreted to result from the enhanced atomic bonding nature among the constituent elements by adding Fe.
