摘要

The influence of the cooling rate on the structure, microhardness, relaxation, and devitrification behavior of Cu_(44)Ag_(15)Zr_(36)Ti_5 glassy alloy on heating is studied in the present work. According to transmission electron microscopy investigations, the structures of Cu_(44)Ag_(15)Zr_(36)Ti_5 glassy ribbon and bulk samples are somewhat different. The structure of the ribbon samples is amorphous while, the nanoscale clusters of the crystalline phase (highly ordered regions) are formed in the bulk samples. It is reflected in the shift of the x-ray diffraction peak, in the magnitude of the heat of structure relaxation and crystallization, as well as in the change in the Vickers microhardness. An analysis of the cooling curve is also performed.
