Nonisothermal Crystallisation Kinetics. Comparison Between Classical And Isoconversional Kinetic Parameters Computing Methods Applied To Ni92.3Si4.5B3.2 Metallic Glass

Differential scanning calorimetry (DSC) is one of the most used indirect techniques in the study of thermal properties of solids. It is widely applied for computing the kinetic parameters describing the crystallisation processes in amorphous materials. There are plenty of methods developed for calculating such parameters, most of them called classical ones, and these are developed in the JMA theoretical frame. a theoretical review on their basis and assumptions is made in order to improve the methods and the reliability of the kinetic information. Crystallisation kinetic parameters computed by methods based on the isoconversion theory are developed this way in an attempt to solve the problems present in the application of classical methods and improve the global description of the crystallisation processes.
