Abstract

Metallic glasses in general have very wide range of technological application due to their strength and corrosion resistant behaviour. Zirconium based binary metallic glasses with Copper and Nickel show superconducting behaviour in low temperature region. A number of efforts related to structural relaxation in binary metallic glasses have been reported, very few studies on the crystallization kinetics have been carried out. The amorphous ribbons of Cu₅₀Zr₅₀ alloy were prepared by a single roller melt-spinning technique in an argon atmosphere. The structural change of metallic glass Cu₅₀Zr₅₀ from room temperature to 750 K is investigated by using Differential Scanning Calorimetry (DSC) technique. The activation energy of crystallization has been evaluated knowing peak crystallization temperatures at different heating rates. The heat of enthalpy during crystallization is also evaluated by the measurement of the areas below crystallization peaks.
