摘要

In the present work, the thermal stability and crystallization kinetics of As35Se65-xSbx (0 <= x <= 10) glasses were investigated. We found that the increase in Sb concentration reduces the thermal stability of the binary As-Se alloy because of the structural change. The HrubATIN SMALL LETTER Y WITH ACUTE parameter of As35Se65-xSbx glasses is greater than 0.1 corresponding to their good glass-forming ability. The glass transition temperature and crystallization parameters were determined with different methods, and it was found that they change with the variation of the composition. In addition, the activation energy of glass transition was calculated for different regimes of the glass transition region and its value is dependent on such transition regimes. The analysis of Avarmi exponent reveals that the As35Se65-xSbx glasses possess both one- and two-dimensional crystallization mechanisms.
