Synthesis and characterization of $$\hbox {Ti}_{{20}}\hbox {Zr}_{{20}}\hbox {Cu}_{60-x}\hbox {Ni}_{{x}}$$ ($$x = 10, 20, 30$$ and 40) metallic glasses are reported in this paper. Glassy ribbons are produced by rapid quenching using the standard copper wheel roller technique in argon atmosphere. Their structural characterization is carried out by X-ray diffraction (XRD) and thermal behaviour (crystallization) study by differential scanning calorimetry (DSC). Results of XRD on both sides of each ribbon sample confirmed that each sample was indeed amorphous/glassy as only a very broad peak in XRD pattern was observed. Metallic glass $$\hbox {Ti}_{{20}}\hbox {Zr}_{{20}}\hbox {Cu}_{{50}}\hbox {Ni}_{{10}}$$ shows three crystallization peaks in non-isothermal DSC scans while other three samples show only a single crystallization peak. The activation energy of crystallization for each sample has been calculated using three available models, namely, those of Kissinger, Augis–Bennett and Ozawa. All the three models gave nearly similar activation energies for a given sample within 10%.

$$\hbox {Ti}_{{20}}\hbox {Zr}_{{20}}\hbox {Cu}_{60-x}\hbox {Ni}_{{x}}的合成与表征$$ ($$x = 10, 20, 30$$ 和 40) 金属玻璃在这篇论文中被报道。玻璃带是通过在氩气气氛中使用标准铜轮辊技术快速淬火生产的。它们的结构表征是通过 X 射线衍射 (XRD) 和热行为 (结晶) 研究通过差示扫描量热法 (DSC) 进行的。每个带状样品两侧的 XRD 结果证实每个样品确实是无定形/玻璃态的，因为在 XRD 图中仅观察到一个非常宽的峰。金属玻璃 $$\hbox {Ti}_{{20}}\hbox {Zr}_{{20}}\hbox {Cu}_{{50}}\hbox {Ni}_{{10}}$$在非等温 DSC 扫描中显示三个结晶峰，而其他三个样品仅显示一个结晶峰。使用三种可用模型计算每个样品的结晶活化能，即 Kissinger、Augis-Bennett 和 Ozawa。对于给定的样品，所有三种模型都给出了几乎相似的活化能，误差在 10% 以内。
