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). (C) 2013 Elsevier B.V. All rights reserved.
