Study of Kinetics of Crystallization of Ti20Zr20Cu50Ni10 Metallic Glass

The paper presents a study of kinetics of crystallization of Ti20Zr20Cu50Ni10 metallic glass ribbon by Differential Scanning Calorimetry (DSC) under non-isothermal condition. The sample was prepared by the standard melt spinning technique, that is, rapid cooling of the melt of the alloy on a rotating copper wheel. As prepared sample was confirmed to be amorphous using X-ray diffraction. DSC results show three peaks, the first one being relatively sharp while second and third peaks are broader. Activation energies of three crystallizations, referred to three peaks in DSC thermograms, have been evaluated using Kissinger, Augis-Bennett and Ozawa models
