摘要：

This work consists of a study on the crystallization reaction kinetics of six alloys in the As-Se-Te glassy system, chosen as representatitve of the easy DTA crystallization zone, within the concentration triangle of the system. The study was carried out by differential scanning calorimetry, using continuous heating methods, and the corresponding kinetic parameters were evaluated by an iterative method based on the Johnson-Mehl-Avrami theoretical model. Finally, the glass-forming ability (GFA) of the alloys and of the system are discussed by calculating the rate constant of the crystallization reactions. © 1990.
