Research Abstract

The crystallization process of Se95−xInxPb5 (x = 2, 4, 6, 8 and 10 at.%) glassy system was studied by differential
thermal analysis (DTA) technique under non-isothermal conditions. The crystallization parameters
were calculated using different kinetic models. The glass forming ability was found to decrease with
increasing In content. The validity of the Johnson–Mehl–Avrami (JMA) model to describe the crystallization
process for the studied compositions was discussed. The results showed that the two-parameter
Sestak–Berggren model SB (M, N) is the most suitable for quantitative description of the crystallization
process for the studied compositions. Increasing In content in the Se-In-Pb system leads to a more complex
and accelerated process. The crystalline phases formed in the annealed samples were identified
using X-ray diffraction technique (XRD) and scanning electron microscopy (SEM).
