Abstract
Glassy alloys of Se90In10-xAgx were prepared using melt quenching technique.
Non-isothermal differential scanning calorimetric (DSC) studies were done on
Se90In10-xAgx (x = 0, 2, 4, 6, 8 at.%) glassy alloys at four different
heating rates (? = 5, 10, 15, 20?C/min). Well defined endothermic and
exothermic peaks were obtained at glass transition (Tg) and crystallization
temperature (Tc), respectively. Augis and Bennett?s method was used to obtain
the composition dependent crystallization activation energy (Ec) and the
pre-exponential factor (?0) of the Arrhenius expression. A linear dependence
between ln ?0 and Ec was observed showing the existence of compensation
effects of the Meyer-Neldel type. These compensation effects confirm the
applicability of Meyer-Neldel (MN) rule for the non-isothermal
crystallization in the present case.
