A novel titanium-based alloy with low density, high hardness, and corrosion resistance was manufactured and characterized in this paper. The Ti₆₀Ni₉Fe₈Co₈Si₁₅ alloy was created from its elemental components and subjected to further manufacturing. To reach a homogeneous phase, the samples were broken into small pieces and were repeatedly re-melted with arc-melting. This base alloy was further processed to manufacture an amorphous/nanocrystalline material by ball milling followed by high-pressure torsion (HPT). For subsequent characterization, X-ray diffraction (XRD), pycnometer densitometry, scanning electron microscopy (SEM) with X-ray energy dispersive spectroscopy (EDS), and hardness measurements were performed. X-ray diffractometry confirmed the formation of a amorphous/nanocrystalline structure, as most of the characteristic peaks related to the crystalline phase disappeared or flattened after ball milling. In accordance, the hardness of the manufactured samples increased by nearly 50 HV compared to the base alloy. The density of the final alloy was measured to be 4.125 g/cm³, with a hardness of 762 ± 39 HV, which confirms that an exceptionally light and, at the same time, hard material was manufactured. In order to distinguish the effects of elemental composition and manufacturing on the measured properties of our alloy, a similar Ti-based alloy with a different elemental composition (Ti₄₇Cu₄₀Zr_7.5Fe_2.5Sn₂Si₁) was also prepared with the same proposed manufacturing process. This reference composition resulted in significantly lower hardness (489 ± 31 HV) at a significantly higher density (5.767 g/cm³).

本文制备并表征了一种新型的低密度，高硬度和耐腐蚀性的钛基合金。Ti ₆₀ Ni ₉ Fe ₈ Co ₈ Si ₁₅合金是由其基本成分制成的，并需要进一步制造。为了达到均质相，将样品破碎成小块，然后通过电弧熔化法将其重复熔化。对该基础合金进行进一步加工，以通过球磨，然后进行高压扭转（HPT）来制造非晶/纳米晶体材料。为了进行后续表征，进行了X射线衍射（XRD），比重瓶密度计，带有X射线能量色散光谱（EDS）的扫描电子显微镜（SEM）和硬度测量。X射线衍射法证实形成了无定形/纳米晶体结构，因为在球磨后，大多数与结晶相有关的特征峰消失或变平。按照，与基础合金相比，所制造样品的硬度提高了近50 HV。最终合金的密度经测量为4.125 g / cm^{如图3所示}，具有762±39HV的硬度，这证实了制造了异常轻并且同时坚硬的材料。为了区分元素组成和制造对我们合金的测量性能的影响，还制备了具有不同元素组成的类似Ti基合金（Ti ₄₇ Cu ₄₀ Zr _7.5 Fe _2.5 Sn ₂ Si ₁）。建议的制造过程。该参考组合物导致密度显着较高（5.767 g / cm ³）的硬度显着降低（489±31 HV ）。
