Sažetak
Metallic glass Zr53Cu40Al7 was prepared in the form of ribbon by melt-spinning the master alloy in a purified argon atmosphere at a lower quenching rate. Its thickness of 0.1 mm is near limit of bulk glasses. Presence of crystallites in the amorphous matrix was confirmed by X- ray diffraction (XRD). Homogeneity and chemical composition were investigated using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). Metallic glasses are metastable and it is of great importance to investigate their stability. The crystallization process was studied by means of differential scanning calorimetry (DSC). Overall activation energies of the crystallization were calculated using various models for non-isothermal process and their values are close to 2.97 eV.
